well, sometimes you can see a person in front of you and he/she just pretends being your friend ... but you won't see it.
And the thing that he/she is in front of you doesn't really help
Sometimes an on-line advice can change your life.
Some virtual friends can't re-place real people, some real people can't replace virtual friends.
I have 2 best friends in my life - my parents. Also I have 2 best girlfriends whom I can tell everything and help them as well.
In the virtual life I have a lot of friends and I'm thankful that I have them.
Also I helped my Israeli friend to talk through the night when the war with Palestine (2009) began. It was rigth after New Year's Eve. I could choose go patying but I felt that she needs my help and we had a serious talk and I managed to cheer her up.
She didn't call her real life friends
It wasn't them who helped her that night.
On the different forum there was a woman, her little 6yo daughter fell of the window and she was taken to the hospital on helicopter. She was in coma and her mom was my on-line friend. We gathered with the whole forum and donated money (not much but sill) and created a "book" where we wrote our wishes, pics, I created an art-work on 2 pages, we did it so she could think about us and see that we care and support her, not only with money. Some people called her.
It was awesome. Her girl "woke up" in a month when doctors burried all hopes. Seeing her with scars but alive was .... wow. This friend of mine said that she was viewing that book when she was about to lose her hope. It was really emotional, esp when she posted pics.
Not gonna talk about people who helped me with my problems but I'm thankful that I met them in the I-net. I talk to them for years. We call each other (from LA... that's pretty far), I send them video greets etc. Real and virtual friends can be best friends, it's different friendship but I don't think that someone can be better or worse.
