I noticed that men who had written a longer note tended to be upset/ angrier when she was not interested. This is interesting to me because I tend to put time into writing a note if I’m interested in a man online. I try to appreciate the directness when someone isn’t interested back, it’s not easy.
But, I do get annoyed with men who send notes without actually reading my profile to know who I am and then get pissy when I’m not interested.
Overall it’s better to send a note back I think. We used to have auto scripts we could post on IRC. That could be an idea dating sites and forums should start using. A quick auto reply would give a response rather than leaving people feel ignored. How they deal with a negative response is up to them. Hope they can handle it with some maturity and grace.
