2.)Having to sneeze and it just won't happen
3.)Looking forward to those leftovers/that piece of cake/awesome food only to realize that someone else has eaten it before you.
4.)Realizing the night before that you have a 10 page essay due the next day.
5.) Sleepwalking in your nightgown and getting woken up by your apartment building's security guard. In the lobby.
