I snapped at my son at one point about his desire to stay in the pool all day. I feel like that happens at least once per vacation and I always feel like "that parent" for getting grumpy with my kid on vacation. But seriously, why are we paying all this money to go places when you only want to see the pool, kid.
I also got nasty with someone who pushed in front of me just before a show was supposed to start and then wouldn't take off her huge Mickey ears. It wasn't effective. She got indignant that I was passive aggressive and refused to take the ears off. Typing all of this out is making me feel like a grump. I swear I am usually pleasant.
