I don't know how it happened, but on our first trip to WDW (me, DD and DH for the first time), I forgot to pack a hair brush. How the heck we managed that, I don't know. I suspect DH took it out of the bag to use and did not put it back in, but he will deny it if you ask him.
Anyway...
I sent DH to the gift shop to buy a brush. It is very close to 10 pm, when the gift shop closes and it takes him a while to find his way there. He comes back with this itty, bitty plastic hair brush that looks like it is for a doll. You know the ones with the slip in plastic inserts that have the bristles????
DD and I have VERY coarse hair, and when I used it to brush out my hair, it made so much noise when DH was sleeping I had to GO OUTSIDE to use it! It took forever to brush out DD's hair.
However, as much as we hate it, I take it to WDW everytime we go and pull it out. No one uses it, but we all crack up.
We are pretty easily entertained, lol!
