I presume a lot of us get messages sent to us from people saying they want to be our friend etc - unless it is someone you know (or at least had some form of cyber interaction with) it is just best ignored - I have had several and I just haven't replied - not to be rude but friendships will develop if and when the time is right.

I am not saying this situation is your fault at all - the things that were said were rude and unnecessary. But to save yourself from any upset in the future just ignore any messages sent to you for friendship.
