During COVID lockdown with:

- my wife

- au pair

- 3 kids (all under 5)

- dog

I thought that was plenty of human interaction (I'm somewhat extroverted) until we had a friend come over and chat with us outside on the porch.

I couldn't believe how, for lack of a better word, "refreshing" it felt. It was an excellent reminder that we are largely social creatures who also need some variety in the social circles we interact with.
