I chose not to have children.

OP-great topic! Thanks
If I can add, if someone says they don't have children please don't make any assumptions about it. Just accept the fact and move on. If you decide that you absolutely HAVE to know then perhaps wait until you know them a little better before asking it. For some people not having children is a choice, others are desperately trying to children, and some can't have children either due to genetic or medical problems. If this is your first or second meal with them, they might not feel comfortable giving you their medical history.
