Do people like your face?

I was playing around with Facebook recently and was pleasantly surprise to receive an invite from a friend who has not been in contact for many years. I was telling Ah Line that it was a very nice feeling to know that people still bother to look for you after so many years. On the other hand, I begin to wonder what if someone rejects your invite to be added in Facebook? That will be an awful feeling won't it, especially if that person also has a facebook account?
