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

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

I remember that I used to mix with my friends who had brothers and sisters. I was an only child.

I was a very observant child. The boys in my books are based on boys in my neighborhood growing up.

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

I was an only child until I was 11 years old, which is when my sister was born. So for 11 years, it was just me.
