Started judo for the first time ever last night. Nothing intense or rough, but more on what to expect from Judo, it's benefits, and some fundamentals. I really enjoyed it and the instructors were very nice, taught well, can't really fault the club one bit at all. I paired up with a mate of mine (we also do kickboxing together) and a third dude (let's call him Hero) who was the odd one out. We invited him over to practice drills with us since we had no partner. It started off well, everyone had fun. My mate and I just going through the motions thinking about the technique and etc so going at it pretty cruisy. Anyway Hero decides to let his inferiority complex take over and starts rough housing us on some hip throws (from the knees to practice falling). We then started to do standing hip throws, falling through, control oppnonent on the ground and work a kimura (is that what i's called?). Now Hero decides to take it real serious, chucks us with brute strength as opposed to technique and starts yanking on our arms. We both told him to ease up and relax but homeboy doesn't listen. Instructor also tells him to relax but again Hero clearly doesn't listen. As retirbution, I went through the drill with Hero, put him in the arm lock, pretended I didn't feel him tap. So put an extra bit of pressure just for giggles. My mate laughed, I pretended I didn't know what was happening and instructors didn't give a shit. Should I be feeling bad?
