I'm polite roughly 95% of the time. Even when someone hurts my feelings, I do my best not to hurt his. If I even say anything, I do it as nicely snd calmly and, well, politely as possible.
The other 5% is what happens when I'm caught in a bad place (usually just after having been hurt). I don't go looking for a target - but I'm less careful about being nice if one presents himself.
So this guy emailed me tonight on OK Cupid. In his "hello" message he said, "What do you know? I was just saying I needed to find myself a short, sarcastic brunette. What are the odds?"
It's worth pointing out that statement is a reference to the last section of my profile, proving this guy actually read my whole profile before emailing me. So, while a quick glance at his profile showed we have differing dating agendas, I figured I should at least acknowledge his effort.
He thought I was being presumptuous - which, I supoose is fair. He pointed out we never really know what someone is really looking for. I admitted he had a fair point, but in his next message he asked, since I know so much, what did I think he was looking for.
I repeated the first line of his profile back to him. Admittedly, I added plenty of sarcasm - but this whole thing did start with him saying he was looking for a sarcastic brunette.
So actually, I was being pretty polite.
