As far as the general subject goes. I'm noticing a lot of possible communication hurdles. For instance when somebody looks or talks. It is easy to be sensitive to this subject, even more so when it's not yourself but a loved one with a need. With said sensitivity it is a lot easier to view each look as "see, they are looking at me because of -fill in something negative/judgemental". Might be, but it also might be somebody checking out a chair/stroller or whatever aid because they have a eureka-moment (cool aid/ never knew it, but that might work for Gran/Suzie/Tom). Might be because they love something you're wearing. Might be that special smile. Might be a hundred things. When you might be used to a 100 stares resulting in let's say 65 being negative, those 35 others are more easily put into the negative category by the way our brain works.
I'm lucky in the sence that I tend to be ignorant to looks, comments and what not unless I'm not my regular selve and have a bad day. I am so consumed with my/our goal and focus I simply don't even notice looks and comments. It has been a huge lesson. My parents, loved ones, friends are not so oblivious and notice it. After stare 100 when for instance going shopping many friends will feel beyond uneasy and feeling judged. Some times that is correct. Others; not so. Result; they feel worse than factually needed. Because I tend to be so oblivious, many times have resulted in later finding out why a stare or rumour happened. Both me and others were and are happily surprised with how many are not what we might think they are.
Also have learned that my own posture is a big influence. When I'm not owning my aid and situation, almost like embracing it and radiating out that "this is totally normal, nothing to be noticed", sure enough other people will pick up on my own unease with it and I do get more stares and comments. Did a trial once with my OT when she didn't believe it and reckoned it would be how I considered things. She followed me while shopping using an aid I'm very uneasy with and don't want to use versus my normal ease with my regular aid. She was amazed to notice the same. Has done this with other clients also to empower and found the same thing.
In a real bad mood? Oh boy......... poor me and poor rest of the world.
In cases where there are meant judgemental stares and comments? Humor is the best medicine. For myself as it brushes things of and turns it into a positive moment and it's the easiest way others open up to the idea that they might need to adjust their opinion or educate. If need be I'll be the first to go totally overboard with that to make sure the point does not get missed. My weird sence of humor and others seem to react to it in a very positive way. Sometimes it will have no influence what so ever on the other(s). As it happens in life. But as said the positive for me is a lot better than drifting on the negative and it tends to result in some nice interaction with others when around.
I am also the one that would speak up when hearing rumour, see pointing towards me but avoiding me like the plague so to say. I'll have a look, scale folks in and either go on my nutty selve of overdoing it and going so overboard with it that the "hint" gets across. Others love to get involved with such a sketch. Other times I'll simply put on an open smile and say "it's OK to ask me something if you want to, it's a lot easier to ask me about me as others don't know my business". Whether I'll answer the question and with what details is another thing, but it has lightened up situations many times. If beyond obvious judgemental? Not going to bother educating, but do use my humor in my own head so to say. In a very rare of such case when all the odds come together (beyond bad humor, beyond bad day, beyond unacceptable comments etc. etc.) I might not be so nice. Snap or stare back or comment back. Not only makes me feel worse eventually but hardly ever helps.
Kids are the best "weapon" ever in this! And there are loads of them at WDW. Kids are open, honest, have no idea of political correctness or whatever. They'll simply make a comment, look or ask. Love that additude and always "reward" it when aware. Will answer questions in an appropriate way, talk with them on their level or engage a look connecting to whatever they are looking at and how. They will simply accept what is or ask more questions if they don't understand yet. Fine by me. Sure enough, most of the times one such kid will result in me seeing lightbulbs going off over the heads of many other adults or teenagers in line. Score so far still results in kids looking (and pointing and screaming about me) more often than not because they have a positive sentiment. Love the fabric of my chair, love something I wear, love my wheels that light up, love my Animal-joystick, you name it. Not just that, but also can't count the times anymore where before you know it such a kid will "correct" or educate an adult or other child when they notice a stare, comment or whatever.
Oh dear, I was just trying to say that my son would be polite and give his seat and it seems to have blown up into something more
