Ask HN: Experience Designing Things as Lefties?

As a leftie, every now and then, I'm reminded of how I perceive interactions differently. Sometimes, I'll come up with some novel design that feels "right" to me, and I'll present them to teammates and they'll realize it's completely mirrored.

I've made my peace long ago with how door handles, scissors, pens behave "wrong", or more specifically how UX is designed for the majority of users. But it does bother me when I create work and it's wrong.

What are your experiences designing things as a leftie and realizing it was off?
