The best apples are at the top of the tree.
Some boys don't want to reach for the good ones because they are afraid of falling and getting hurt. Instead, they just get the rotten apples from the ground that aren't as good, but easy.
So the apples at the top think something is wrong with them, when in reality, they're amazing.
They just have to wait for the perfect person to come along, for he will climb all the way to the top.
