there are actually so many examples of how bothering someone is, which determines what kind of reaction I'd take. one instance when I was in college, my senior kept touching me on my shoulder or patting my head (no he didn't have any feelings toward me, he's just annoying af) that caused me feel extremely uncomfortable around him. I didn't confront but showed him that I was no longer interested in befriending him. I stopped talking and cut him off. another example someone was bothering me so much like out of this world and all I did was confront and let my anger out. that was the one and only time in my life I was being the most most rude person ever existed.
