I was an only child, but I did have a hell of a lot of cousins.
If you have no brothers and sisters it defines you for life; even when you're thirty you refer to yourself as an only child.
I was an only child; I didn't have a sister, or sisters.
I was an only child, eventually.
An only child is never twelve.
I always wanted a brother.
I always wanted a sibling.
My husband is an only child of only child parents.
I don't mind being an only child; never have. I am lucky, though, that I have my friend Emily, who grew-up very close to me and so, there is someone I have shared memories with. I would miss that if I didn't have it, I think.
