but you are cute"

This was said to me today. I was caught off guard. I had no prepared appropriate response. Sadly, when I wear the dress I am wearing today I have a canned response ready for any rude remarks, whistles, etc. but this I wasn't ready for.

I said "Thank you."

"Thank you."

I keep turning it over in my head and I feel that his intentions were to simply compliment me. His gaze did not make me uncomfortable and he met my eyes when he said it and walked away after.

I just don't know if it was appropriate even with the "I don't mean any harm" opening or am I being overly sensitive since I'm usually on high alert for cat calls.
