Do I know you?
When I first started on Facebook I spent time searching for people to add as friends.
But after a while I stopped actively looking as I figured I'd added pretty much everyone I knew.
These days I often get friend requests from people I don't know or people who I may have just met.
Sometimes I accept them. Sometimes I don't.
But I'm pretty sure most of us have one or two Facebook friends who we don't know very well.
Don't believe me?
