my gym teacher is testing me

my gym teacher is sending my parents emails for the stupidest reasons. today he emailed my parents because i wasn't bringing my gym clothes for a few days. one time i actually did and showed him my gym bag and he didn't believe me because "they weren't wrinkled". just because you don't iron your clothes it doesn't make it my problem?? he's so dramatic for no reason, and he insists on making my class do gym outside. also today it started raining while we were playing football and some of us ran to get our bags, and he made us wait outside in the rain while our stuff was getting wet so he could deliver his speech about our attitude, he was like "if you think i'm such a horrible teacher for letting you out in the rain, you can stop being dramatic. no one has ever died in this class, and if you think i'm such a horrible teacher you can tell your parents and make me lose my job😡😡". he needs to stop yapping, genuinely
