I tend to treat online friends a bit different also-initially anyway-though not in a bad way....Out of the 4 years I've been participating online, there is only 1 person that I still talk to on a regular basis, both on and offline, out of maybe hundreds talked to, chatted with, etc...Everyone else has basically come and go, not necessarily anyone's fault, it just seems to be the nature of the beast...Folks leave, transfer ISPs, all kinds of things that might cut a connection short. But I think it's always nice if you can connect with good people, no matter where you meet them. You just never know where that good friendship is going to come from!!
A friend is someone who can tell you the truth, no matter how much it hurts, will stand behind you no matter what. Friends are our chosen family.
I do treat online friends differently than real life friends only to the point of most online friends we will never meet, although some of online friends have turned into real life friendships albeit a small %
