This happened a few years ago.

Edit: I'm a man (barely). I'm the father in this situation, guess that wasn't clear. Anyway:

When my son was born, I was working from home. This was pre-pandemic so it was a little more of an unique situation at the time, at least where I lived. Since I was the one working from home, I generally did most of the childcare stuff. My job at the time was pretty flexible so if I disappeared for a little while no one knew or cared. As such, I would take my son to the park or grocery shopping or whatever as need arose.

Every time...and I mean EVERY single time...some boomer would ask "Oh, is it mommy's day off?"

One day, I was at the grocery store checkout and my son was being very fidgety. I was trying to manage him and he was just in a straight up pissy mood, which wasn't helping MY mood. Sure enough, at the worst possible time, I hear it: "Must be mom's day off!"

I turned around and saw this old lady smiling at me. Without missing a beat, I said "My wife had an aneurysm while giving birth and passed away. Every day is mom's day off."

She started apologizing and I just turned around and continued checking out. Maybe an anticlimactic ending, but I felt good about it for weeks afterwards.

By the way, my wife is fine.
