then find something else to do
draw, paint, think of stories, sit outside, PLAY OUTSIDE, meet up with a nearby internet friend, sit in the supermarket for hours a day, draw the hobo by the carwash, try on all the shoes at a shoestore
there are a bunch of things to do, you just don't want to do it?
mom wont let you outside? convince her.
still doesn't let you? just walk out.
