For sure. I had a woman seriously concerned telling her I am an only Child. Her response was that when I would die my parents would not have a 'backup' kid. 
She was from a very rural area and it was normal to have at least 2 or better more.

I'm an only child too. My son is fourth generation only child. I got all those concern trolls when I was growing up and my mom was a career woman. The neighborhood ladies who were all SAHM "But if your mommy works, who takes care of you and your daddy?' I would just roll my eyes. I was proud of my mom.
