I'm an only child, so I don't even have nieces or nephews.

I was an only child of a father who loved me deeply, but we didn't play catch, even though I was an athlete. We didn't go fishing or hunting or any of the things I wanted to do. Why not? He just didn't do that.

I was an only child; I didn't have a sister, or sisters.

I don't drink Pellegrino and Perrier, but my nieces and nephews do.

I've got loads of nieces and nephews.

I was by far the youngest of the family, and at times it was like being an only child.
