Weirdest thing your partner noticed about you?

Sometimes our partners (or even just good friends) know us better than we do. They spot little quirks that you'd never noticed before.

For instance, my partner pointed out to me that, whenever we see something tall or high up, I always describe it in terms of how lethal it would be to fall off it.

"It's a tall bridge but i think you'd probably survive the fall." "Man, no way you'd live if you tumbled off that pedestrian crossing."

Etc.

I had no idea I do that. Now I can't unknow it.

What does your partner know about you?
