Thats ridiculous, smart cookie. MOST people including myself would never accept a friend that they don’t know. And that person who went off the derech – don’t fool yourself, with or without facebook they would find someone.
As for freezer, I don’t have time for meaningful, long conversations on the phone. I have a 6 month old baby… 5 minutes on facebook is all I need to keep up with a whole bunch of friends.
