As the only left handed member in my family, I'm now curious if I ever did that to my family. Though for tasks of that nature I may actually use either hand, or maybe I just started using the right hand because I was the weirdo (asking my mother she said she never noticed but assumed I probably just adapted and used my right hand).
As a bachelor I virtually make all my own bread so I don't really notice, but I think I do take time to figure out which way to twist before opening so maybe that is a thing.
This is just to say, the things you never think about, and I enjoyed the irony of your situation from the reverse side.
