That's almost like a full time job right there. I wasn't in band, but I was in a show choir kinda thing (I can't really sing that well, but I could lift girls for choreographed stuff, so you know), and the school band and the show choir went to Disney World together one year. We were supposed to be in a big parade thing or whatever which justified the field trip, but then the parade got cancelled so we literally took a school trip to Disney for no reason, which was pretty funny honestly. Sorry if that seemed random, your arts festival thing just kind of stirred up that memory haha. Pretty cool you guys got filmed and put online though, you have now been immortalized on the internet.
And yeah, I'm not the head instructor at the dojo, but I teach a children's martial arts class on Monday nights. The age range is about 5 or 6 years old to roughly 13 years old. On other nights throughout the week I take the adult classes there though. I've been in it since 6th grade at the same dojo, but there was about a 5 year gap in there at one point because my work and school schedules just wouldn't match up with the kenpo schedules. I do like it though, I'm not really into sports, but I've always held an interest in martial arts. It may not be a bad idea for you and your brother to take some martial arts classes, if anything you can probably call a dojo close to you and if you ask they might let you try a class for free and see if you like it before you sign up.
