Some people are like pimples. First they start to grow on you; then they mess around w/ your moods, they bring pain, constant irritability and annoyance; that, then they make you feel ugly, and everytime that happens you just can't do anything about it; some are just terrible.. especially those in favour of leaving marks behind to remind you of how they hurt.
But then again when they're gone, the world's a MUCH happier place.
