My parent's are thinking about buying me a snow cone hut thingy?

I don't know how to tell them, that I don't want one. They're so excited that they think I want to own my business like father, like son. No. It's a snow cone hut....he doesn't own a snow cone hut...why would I want one? I'm only a senior in high school. Do you think I should do it..besides I could always hire other people to do my job..but I don't want to fail miserably.
