I hate it when you are opening presents and you get something that you sooooo did not want (thinking for sure you were getting something else) and it is so hard to look like your happy and hide your instincts to look sad -_-
I hate it when I'm SOO excited to ride the next day, then look outside and there is suddenly 4 inches of snow... OVERNIGHT. (that happened a few days ago.)
I hate it when I decide to go for a "quick ride" with my mare and have to spend 3 hours grooming her since she decided to go swimming and cake herself with clay mud from head to toe (conveniently matted into her winter coat).
