I've got loads of friends, all of whom I'd count as "proper" friends, plus a much wider ecosystem of people I know and am friendly with but wouldn't tell my darkest secrets to.
A quick squint at my Facebook page tells me I have 57 friends, about 40 of whom I'd count as "proper"; and I have lots of "proper" friends who aren't on Facebook.
A gang of about 30 of us all shares one email address which we use for arranging parties, meals, birthdays etc. That's important glue between us. Guess I'm lucky!
