I hate that when you return from vacation you have so much to do that it instantly wipes away any residual relaxation you might have been hoping to carry over into real life.
I hate that soy milk isn't available as a pour-it-yourself-like-creamer option at coffee shops.
I hate that students don't believe sexism still exists. (Silently wipes away tear, burns bra)
I hate taking over-the-counter medicines. Like, for instance, if I have terrible heartburn and I can't sleep, I will wait for up to three hours before dragging myself out of bed to take some pepto bismol rather than just doing it right away. I also hate taking tylenol/ibuprofen/whatever for headaches.
I hate yoga. Recently I talked to a friend who has to call it "stretching" in order to do it. I am going to adopt this practice, too.
I hate that you have to stay at work for eight hours, even if you are really, really efficient and get tons of stuff done in three hours. It punishes the quick.
I hate it when people leave voice mails just asking you to call them back and not telling you why they are calling. It makes me nervous.
I think I could continue this forever. I hate a lot of things.
