I find that there are some things which I should really ought no know already, like how to balance having friends and a boyfriend. I manage neither of those spactacularly well on their own, but when I have both on top of non-relationship activities, I always end up feeling like I have screwed somebody over.
It's like an "I Love Lucy" episode. No matter how much candy I eat or wrap off the damn conveyer belt, I am never on top of it enough to have done a good job. Bah.
