I think forums are similar to real life, you make some friends and lose friends. Foe example - how many people still are in contact with friends they made in (for example) primary school?

I'm no longer in contact with anyone from school at all, I'm facebook friends with a couple but we dropped off each others radar apart from facebook.

This thread reminds me of when one of those friends and me, when we went into high school, we both promised we'd keep in touch, I wrote letters to her for a bit but she never responded so eventually I gave up and stopped writing to her, cause I figured she had lost interest in the friendship we had.
