I have a few that have lasted...though it's true that I might only hear from them once in a while. i find that a lot of people just get to the point where they aren't on here as often. Or they keep accumulating new friends and go through the same process with them. Maybe we are all looking for a sort of connection that is hard to find, especially online. Most friends are kind of "passing through". Seems to be the nature of EP, and I've gotten used to it. Fairly often, life is like that too.
Close ones stay the same. Some I cherish but fear losing for loss of contact.
Some of my friends date back to when I first joined over a year and a half a go, some are are new, some are medium term and a lot of good people have gone.
Never thought of EP as a place to make friends. Just a place to waste idle moments of time.
