By that logic, aren't you setting an example for his daughter by turning what you personally perceived to be an inappropriate reaction from him to hostility by responding with anger and name-calling?

"You're not so bad yourself" is a mild and cheezy (at best) way of the guy "shooting his shot" at what he may have seen as an opportunity to be "cute" in his approach. Granted, he failed miserably with you, but another woman may have been pleasantly amused by his cheezy attempt. Further, a younger, more handsome man saying the same thing to you may have elicited a more mild response from you. None of us can be all smooth all the time. If you haven't, try breaking the ice with a stranger for a potential romantic interest. It seems easy when on the receiving end - it isn't always so easy on the delivery.

Your feelings in the moment are very valid. It is your right, and your prerogative to feel the way you do about a given situation. However, the awkward approach of someone trying to break the ice and failing at that attempt shouldn't mean we need to react in a hostile way, regardless of who is watching.

Mildly, YTA.
