Little different for me.
I was bored on facebook at 2 am one morning, went on facebook, typed in my family's last name (not mine, but the rest of my family), which is a very unique name and the results were basically 3 people in america, and like 40 in germany. Then I realized one of the girls from america went to college with me, so I friend requested her, invited her over, but left out the detail that my families last name was hers, and we might be related, and in fact I knew her family was at our family reunion. I told her later on, after I invited her over.
