The one that got me was being called “that man”.

My dad is “Mr. <our surname>” and he thought of his dad as the same, but both he and I have courted and expected the same title in various places and if you’re called that name enough times, you can kind of get used to it.

But when a small child almost runs into you and their mother chastises them with “Careful! You almost ran into that man!” and “that man” is you. Oh boy. And another time “Why does that man look so sad?”. As you might imagine, I was not having a particularly good time before that small child said that.

But I suppose it wasn’t “that old man”…
