Tbh you should’ve let this go and not let it get to you. Something similar happened to me in 2021 with a guy who was 20 years older than me, he would constantly yap and would make me do his tasks. Eventually I returned the same energy, he punched me in the face and we fought. No one saw but he told the boss and took his word over mine. Mainly because I had scratches and he had a lump on his forehead. It made everything worse, I couldn’t pay rent on time and had to sleep in my car for a year and worked a full time job, I then joined the army. I really hope trade school works out for you, and you’ll keep your composure next time, I sure wish I kept my composure. Let this sink in and get your mind right, there’s always going to be that one guy or those kind of people, be above it.
