I find it very interesting that in a post about smiling, there were comments about how Russian people aren't fake so they don't want to smile just to be polite but here you wish to write people to let them know you are not interested. Which is just another fake form of politeness. I can understand in person you having to say something as you have been confronted but online move on...Men aren't fragile, we know rejection is part of the process in trying to meet women. I would rather a woman move on and not write me than to get a courtesy letter saying thank you but no thank you. I have not gotten a rejection letter but then I don't initiate letters, I am lucky in that I have been approached myself here almost exclusively but I did recieve a message once saying a woman rated my picture a 10 and I do as I usually do and said thank you, to which she replied, oh I just liked the picture I am not interested in a relationship with you, and I thought well that was rude, I wasn't asking her for that or interested in the slightest, I just was being polite. If that was her being polite back I could have lived without it lol. If you're interested write back, if you're not get on with your life. No guy is losing sleep over not hearing back from a woman he barely knows or doesn't know.
