That's easy man, do what they say and do any high school sport, but play the worst you can, and then they realize that you suck and belong to a mx track, everytime you ride, you gotta behave for them to see that you deserve more to pursuit a dream.
btw, how old are you?
haha that's a good idea actually
and I'm 14, 15 in 6 months
i wish to be 14 again, i had such a blast at your age. Just an advise kid, enjoy your childhood, don't do drugs and get focus at school, even that's boring sometimes, one day when you start to work, you'll figure that school was the best time of your life... you're only young once. Enjoy your life, twist the throttle and smoke them all!!!
