Kristina She Doesn't Know I Exist

I hate those questions on Facebook about how well do you know your friends. I feel awful not knowing the answers. It makes me feel that I don't know my friends well enough. Its horrible that you can have over 600 friends, and 88 friend requests, and 20 friend suggestions but you don't know the particular person well enough. It might not be very significant, but they whom made those questions might questions the values of the friendship we have. 

Now, knowing that Facebook is no longer for friends; its all about networking; tell me something- what should I do, what should I know my friends? 

Do I know you who read this page, and do I know you well enough?
