My first girlfriend whom I met at age 4 found me via FB. I have not stayed in touch with her since 2008 because her phone number was in my old Palm Pilot in the age before the Cloud. Obviously, now I do not keep anything other than in the Cloud ever, but back in those days... and I do not have the charger for the Palm Pilot anymore - I have long been on various Android phones. So that is how I lost touch with her. I was very happy to receive an invite from her and will see her in May - happy end.
