Not that I know of

I meet a lot of new people. Often in the context of somes sort of Christian ministry. And they often ask me, "Are you married, do you have any kids?"

I almost always say, "No wife and no kids... at least, not that I know of." I always think it's funny, then I realise it's more awkward than funny for the other person and then I get awkward.

But then I forget and I say it again next time I meet someone.
