With all due respect, I think a big deal is being made of what seems like an honest answer.
Someone posted earlier that guys are quite adept at sticking their foot in their mouth and, being one of those guys, I can say it is true. That, however, doesn't mean the guy in question was being rude or disrespectul, and the second encounter probably proves this point, since he was being so attentive.
Also, if someone doesn't want to hear a truthful answer to their question, why ask it in the first place?
Listen ladies, some of us males don't have the intelligence make up to play mind games, especially when interacting with you, loveliest women. When you say no, that means no, right? It doesn't mean maybe, it doesn't mean try harder. So, please give us a break. Mind reading belongs on a stage, not in the bedroom.
