3 Simple Rules

I really like crossword puzzles. Call me a nerd, call me a geek, just don't call me while I'm working on my crossword puzzles. There are some simple rules I follow:

1. I use a pen, never a pencil.
2. I never look at the answers while working on a puzzle.
3. I don't like having other people help me unless I ask.

Why all the rules? Working on the puzzle is a challenge and having the option of erasing answers or having the answers nearby or using someone else's brainpower is like cheating.
