How to convince my mom to let me ride my bike?

Tell your mom that she needs to get up and ride to school with you and then go back after school to ride home with you. Tell her that she needs to do it or her rear end is not going to fit through the door. Oh well, you can use other words like I am worried about your cholesterol and your blood pressure. Or, look mama you used to be so thin and beautiful, lets work out together.
