There is a gal I know, who won't eat alone and she is around her 50's. The newer generation, are in so much constant contact with email, facebook, cell phones, etc. they don't seem to know how to handle alone.
I grew up spending a lot of time alone. Tv as the babysitter after the abduction, neighborhoods where other kids were much younger, non existent, girls, or some combo. I actually feel more comfortable eating alone, then I do in a group. Movies, I attend so rarely, that it normally is alone and towards the last showing of the night.
