Hello! It's nice to meet you! I am an only child and have no siblings, how about you?
I have an older brother and a younger brother, but when I was younger I was kinda jealous of only children!
Ah, so you had a first degree relative, as they call it.  Interesting!
What does that mean, first degree relative? Like an immediate sibling?
Yes, a sibling is considered a first degree relative.
Did you enjoy being an only child?
I did.  I didn't have anyone to argue with and life was pretty easy.  I sometimes with I had a close emotional bond with someone like a sibling, but my life was good.
