Bad parent?

So really.... Does it make me a bad mom when broody teen boy goes outside, with his skateboard in hand, saying, "Hey meem..... I'm going outside to skate....... I'm going to try and land <some impossible skate trick> and possibly injure myself a lot. Is that okay?"
And I'm all, "Okay! Have fun!"
No, he didn't land the trick, but he didn't hurt himself either, other than the normal scrapes and bruises any way..... I must go meditate on this.....
