How much real outside interaction do you get? (not with family)
I could probably go weeks with only talking to my kids/husband/mother and gym partner. But I have friends, but we only see each other about once a month.
I guess I can count the people I train at work. But its on the phone, I don't really see anyone and its teaching more than actual interaction. And I either do that a lot (lately) or not at all for months.
