Ah, the practical kind. I used to study Krav Maga but stopped at E1 both to focus on other things and because I hated teaching. Good luck and hopefully you can only prevent harm to others rather than become involved in a bad situation because of this.
Just got a job offer to teach martial arts in a dangerous part of the city (I live in Mexico, so I'm sure you can imagine). Pros: Pay is amazing, I can teach people over there how to defend themselves, the head instructor will help me attain even more martial knowledge. Cons: High risk of injury and death. I accepted, I hope I made the right choice.
I guess the concept of friendship has changed :") Today I saw a very quiet boy getting bullied by his 'friends' because he wasn't talking. They made a circle and made him sit in the middle and were nagging him saying hey talk, sing a song, do this tongue twister etc. etc. And I could totally see the discomfort in the boy's face. Glad I don't have 'friends' lmao
