Oh, being young! When you're a teenager you always need to find new ways to express your rage or else you bottle up those feelings and say wrong things to wrong people at the wrong times! It's a delicate balance and to keep it in order, you need to master the art of "gettin rid of extra rage". Some do it by knitting and some do it by throwing stuff! But not to harm anything, just to take the edge off! You can join those rascals in throwing things to an apple tree. Try to hit the apples, bee hives, stars and hearts.
