@ Raven : There is a thread about OKC that might be helpful to you. Search for OKC.
As for the girl, I think being 'recognized' tends to panic people, and they shut down. Especially if they are recognized through their place of employment. Go in, and act like nothing ever happened. for me, I wouldn`t offer 'recognition' in person, after she shut-down online already. If something happens to change, then be open to her change of heart.
@ Andy : Some people like you, do find it rude when they aren`t responded to. The best way to avoid feeling annoyed, is to put yourself in another person`s shoes.
#1- OKC has a feature that allows you to know how often someone responds to messages. If you don`t like those stats, stay clear.
#2- MANY times, a simple 'no thank-you, take care.' is responded to, yet again, and even may include insults. There are some folks that find that hard to deal with. It`s better for them not to respond at all.
#3 - If I am at a party, and conversing with someone who I end up not liking much, I probably keep on mingling. I probably wouldn`t go out of my way to walk back up to them and say; ' Hey, I don`t like you, just thought you should know.'
..sometimes we put odd rules on each other, with dating sites. I think this is one of them.
It`s the equivalent of telling people they have to answer the phone in their house for every single call, and have to answer the door to every salesman.
Anyhow, just another POV. Like I said, there is a pretty good thread in exsistance if anyone is curious.
