How long do you go without talking to anyone?

For those who keep track, how long do you typically go without speaking to anyone?

So far this month I've spoken to one person. Last month I think I spoke to others on one or two days. (I'm not including saying hello in the shops, or JobCentre appointments here).

Last November, I spoke to other people only once, and I didn't speak to another person at all in the whole of December (again excepting 'hellos').
