<human>: Today I got in an argument with my friend and in the course of our discussion she said something to me that made me realize that I had the wrong attitude for a long time. The story behind that is that someone at college who I've made a genuine effort to be nice to (because she is mutually friends with my friend) had butted into my conversation and called me out for being a bitch. I was sorta bitchy, it was early in the morning and we were in physics. I digress. I was pissed at this person because she didn't extend the courtesy that I extended to her because of our mutual friend. I was mad at my friend for defending her as well. She kept saying I needed to not let other people bother me. I'd been given this advice many times but at that moment everything fell into place. I had been making things harder for myself. I was upset over things that didn't even matter. Those people don't care if they've upset you. It doesn't mean anything to them. It just clicked.I needed to let go and not care what other people think about me, because in the end, you know who you are and what's important about you and whether people think you're a bitch or not is irrelevant. This seems obvious but its taken til just now to sink in.
Anyway. I wanna read your stories!

Can you condense the text into three sentences or less?
<bot>: My friend told me not to give a fuck about what people say or think about me and wear my bitchiness as a badge of honor. It finally clicked in my head and now I wanna read yours!
