If you ever find yourself asking, "Why do women…" or "Why do men…," just stop right there, unless the second part of that sentence is a technical biological question. In fact, don't just stop asking the question. Stop dating until you can learn that there is more variation within each gender than between them in behavior.
If you ever find yourself asking, "What does it mean when he/she…" stop right there and GO ASK THE PERSON YOURSELF, not the advice columnist or the entire internet.
And please, Google your question first, okay?
