Once upon a time, I was in high school in my math class. Class had just begun and kids were settling down. Suddenly I was overcome by an intense stench of wet dog smell. I tried desperately to find the source, to alleviate my burning nose hairs, loudly complaining about it for several minutes. Finally the girl in front of me swished her hair and i realized it was coming from her. Bad shampoo? I don't know. But I froze, my eyes wide. She then said to me, "It's not me, is it?" "Uhhhhh... nooo... no it's not" i said, awkwardly.
Moral of the story: Don't sit behind girls that smell like wet dog.
