When you cluck/kiss at everything to get it moving! (My horse friends always complain that ___ is not a horse, but I can't help it).
When you miss the barn, you find the coat you wear to the barn and just inhale barn scent :).
When you're talking to a horse person in front of other people and the other people look totally mystified.
When someone expresses interest in riding, you have to hold yourself back from ranting about how amazing riding is.
You have to recommend riding to every single one of your non-horsey friends.
When you get bored in school, you think about riding.
Every exercise is to better your riding.
