I'm an introverted person and I have a difficult time to be confrontational to anyone. So many times I hate myself for not being confrontational, but then I feel like the other person needs to hear how I feel when they do something annoying.

So I am pretty passive-aggressive myself. I prefer it that way and it's more comfortable for me. But it doesn't solve anything with the other person and I feel like they can hate me even more by me being that way. So that would make it worse for me whenever I "bump" into them when I go about my way.

I personally hate it when people are passive-aggressive with me. I'd rather be hollered at or be told off (or even cussed out) than P.-A. At least when I get told off, I could get my words in edgewise with them back. And then it's possible that our conflict or dislike for each other be resolved. It's happened that way for me before. Just my opinion.
