What's the weirdest thing your partner does that you've just accepted?

When I was married to the last ex, there were a lot of things. Actually, I was forced to accept things that weren't normal in any way. ONE of those things was what I call the 360* head flip. The ex would be driving or something and we would just be talking, and all of a sudden he would just fly into a rage. It was so extremely shocking to me that I could not imagine one thing I had said that could have caused it.
