How do you make your parents get you your own horse if they think your not ready?

You can't make your parents do anything. They must think you are not ready for a reason. Are your responsible? Do you take care of any animals you all ready have or let your parents do it? Do you follow directions? ( you can get hurt or killed on a horse if you don't follow directions). Horses are expensive and they are expensive to keep your parents may not be able to afford a horse. Instead of moaning and groaning about getting a horse show your parents you are old enough to take care of one by doing things around the house and talking to them.
