yo i hate this dipshit pt 2

okay so we hop back on minecraft hoping to have another good time with no chaos right??? no, I had gone in the mines and came back with a stack of diamonds and 1 singular one. I had put 6 diamond blocks behind my bed as like a luxury/joke, and this greedy ass annoying ass kid comes and pulls up, takes my blocks, runs and when i catch up and almost kill them, he combat logs. I spent an hour waiting for him to rejoin so i can get my diamond blocks back and somehow, everyone takes his side???? they said i shouldve hidden it better or something but i wanna play this game in hopes without having to worry about hiding my stuff, pmo to the max.
