[Stupid excuse that] "...She was just playing hard to get." And, unfortunately, a number of juries and judges who agree that, short of hitting him in the solar plexus and screaming, you're "going along with it".
This is why some colleges have been publicly emphasizing that "No means No." There are many men who actually believe that, unless you reply in a way that is
clearly antagonistic, "no" means "maybe."
A polite "No, thank you," falls into this "maybe" category. We Ehellions need to find a way to be clearly antagonistic without being rude. It's a fine line. To say "I'm not in the habit of playing scrabble with strange men" sounds like you might feel like changing that habit. How about:
I never scrabble with strangers.
You do not meet my standards.
You are not my husband, and I scrabble only with him.
Or the silent, fish-like stare, meaning, "WHAT did you just ask me?"
What else, fellow Ehellions?
