Should people maintain their friendship if they have disagreements?

Personally, I believe that people could keep their relationship despite reqular arguments.

Actually, people argue with each other about random and trivial stuff, like what food to eat, which movie to watch, and stuff like that. For example, I once argued about which movie to watch with my friend. I wanted to watch an action movie. However, my friend preferred a comedy. After that, I got angry and really annoyed, but later I realized the real cause of my anger was not about which movie to watch, but it was about my papers due next week, and I couldn't stand that pressure. So I apologized to my friend, and we are still friends now.
