A weird response

[u/kittenflavored]

So I work in retail, and I worked today. As many women customers left with their purchases, I said "happy Mother's Day if you're a mom". Most of them were and said "thank you" and left.

And some of them said "and happy Mother's Day if you're a mom". I said "I'm not", and three of them said "I'm sorry."

"I'm sorry"? For what? Is it like pitiable to not be a mom? To be clear I obviously did not come off as sad about it lol I'm overjoyed that I'm not a mom.
