How much time do you spend around people?

By around people I mean social events, work if you're in an office/building site/kitchen with other people (i.e. not work from home), and being at home with family or housemates. Anytime you might reasonably expect to have to talk to those around you. I'm not including walking down the street or sitting silently on the bus.

For me it's about 5 hours a week, maybe 10 if I go out with the walking group, but because it's all voluntary engagements (hobbies, meeting friends, etc) I think people sometimes get the impression I'm really extroverted. But really it's only because I work from home (no calls) and live alone that I can manage that much. When I lived with a partner I managed a lot less and would get meltdowns from lack of alone time.
