Christmas, Valentine's day, her birthday, your anniversary. Don't forget those days. They are a big deal to a chick. (Modify for religion). Single chicks you have a relationship with tend to think of when you met as your "anniversary". If you forget when this was, ask her. This is one of those things that guys think aren't a big deal, but not chicks. Chicks expect flowers, a gift, or something special on these days. The reason is that in your relationship, they envision themselves as having "given" something to you - to wit, themselves. They expect something back. Don't be fooled if they appear to agree with you that valentine's day is just about commerce - they want those roses. I got dumped once on valentine's day. She called me at work - I was stunned. This was about 4 pm. Then someone in the office said "do you know what day this is?" I said no, and they told me. I thought: oh I get it, she waited all day, and when nothing came through the chute, she acted. Too bad - she was quite a chick - owned a Jensen and an apartment building in her 20s, had a high IQ, and was an advanced skier.
