Edge Pieces

They are the second worst. The worst, of course, are corner pieces. People get mad at me a lot because if I am the first to take a piece I will carve it out of the middle. And just to be even worse I’ll often do it in a triangle or circle or something.

How do you feel about edge or corner pieces? Do you cut everything in nice squares or do you just take whatever shape you fancy? Why would anyone want to make the pan that makes all pieces edge pieces? That ruins the whole batch!
