How do you make your mom and dad give you what you want?

You don't. Your parents job is to make sure you grow up to be a good person. If they gave you what you want it may not be what you need or you could get hurt. Children don't have the experience to know that some things they want are not safe or can't be done for different reasons. Let's say you "want" to play on the freeway. Playing on the freeway can kill you so your parents need to stop you. There are many reasons why your parents don't give you what you want.
