Cuz he disapproves of anything that has a slight chance of injuring us
well, tell him this: i've been practising parkour for 5 years and, guess what? i never ever had an injury, the worst i got was a cut from climbing a wall. The very discipline behind parkour forbids you from trying a move or a jump you still dont completely master without trying it first on a safe place, more specifically, near the ground or inside a gym. I get hurt more often playing football with friends than doing frontflips and vaults and whatnot out in the street. If you get hurt during a parkour session, very rarely will be due to bad luck, trust me
