What? GaG's leave? That's it! I ain't accepting no more friend requests...so don't bother...lol
I think that probably depends on the type of social person you are...?. what you demand from your relationships in order to consider them friendships?. I've noticed that some people don't develop any real emotional ties to internet 'friends' while others don't differentiate much between internet (pen pal) friends and real time friends.
I haven't been here long enough to develop and really strong bonds, but I'm sure I will in time and then, Yes, I'll be sad if/when they leave
One or two, I've gotten close to. They know who they are. But I never get upset when people leave. Life is a transient temporary thing. People will leave all the time. You just pick yourself up and get on with it.
Most of the people I talked to a lot keep in touch by text or email even if they aren't around here much anymore. Those that just disappeared, I don;t miss... They didn't have enough respect to keep in touch, so who cares where they went to...
