I'm an only child.  No siblings.  Just me, myself, and I!
Did you enjoy being an only child, or do you wish you had siblings?
Even though the term generally applies to those who've never had siblings, I actually have.
Which term are you referring to?  I am confused.  Do you have siblings or not?
Well throughout history, only children were relatively uncommon.  I thought it'd be interesting to be one of those.
I see, you are saying that the preference was to have many children if possible and a single child was considered uncommon.  I wonder why that was?
Well it's different in China, where from 1979 to 2015 the one child policy restricted most parents to having only one child.
