Sounds like something my mom would have said. She was a bit of a card. One time the family attended a social event and a lady tried to break the ice with my mom:

Lady: “So, are those your kids?”
My Mom: “oh, those are Bob’s kids from his first wife.”
Lady: Awkwardness, followed by finding an excuse to leave.

We were Bob’s kids and my mom was Bob’s first wife.

“What’s this?”

“A picture of us in the future.”

“But I’m not in it.”

“Exactly.”
