I got approached by a lady at a party, and she asked my why I kept ignoring her friend requests on FB. I barely know her face(our social circles almost overlap) and had no idea what her name was, yet she must have requested to be my friend several times, and I hit ignore several times. I said "I didn't recognize you from your picture and I also don't know your last name (even though I didn't know her first name either)." She was offended, because she must be a pretty big deal.

I told my wife it is lying to the world if you have someone your friend list and really aren't their friend.

FB is great for looking at your friends' pictures. I think it is pretty fun for that reason alone.
