Don't you feel some times that you don't deserve to be treated the way how you're suppose to? Don't you feel like people taking advantage of you? If yes, then how would you react? Prolly you would react the same way as that jerk reacted to you right? cause why would a jerk deserve to be treated nice by you when he himself acted stupid towards you.
You see, that's the problem with me. I hate it when I have to be rude to someone and I hate it when that person made me do it. I really hate it. Sometimes I see myself as the most fucked tup person ever. So what do I do to handle it? I simply will wallow one whole night, I don't sleep, I probably will cry and let it allllll outttttt from my chest. Then, I'll make sure that it won't bug me ever again.
Don't waste your time and energy being the same level as them. Just let it go. Just say whatever and continue living in your life.
