I think what is hard for kids to understand is that most parents want to support you in your activities and begin to feel passionate about that activity. I think you guys understand that part actually, but not the corollary, which is that most parents will transfer that interest and passion onto a different activity if you quit pursuing one thing and pick up something new. If my daughter told me tomorrow she was giving up softball and pursuing singing or archery or debate, I'd be sad, but I'd also be like, "OK, let's Google debate and figure out how it works and how I can support her!" Again, I say MOST parents because there are some living out unrealized dreams vicariously through their kids and things, but those are THEIR issues to deal with. You need to follow your heart. Don't underestimate your Dad and his love for you. He may need a minute, but he'll still be your enthusiastic Dad who is "all in" for whatever you choose to pursue.
