Toilet Vs. wheel
The Toilet is for people to go to the bathroom. If you dont have a toilet you will see things you dont want to see things you dont want to see. That is every place that you walk.
Also If you dont have a Toilet you will go to the bathroom in your pants and change them all the time. Next Also you will not be able to use the bathroom and the air will be bad and you cant breath. Finally One reason you need a Toilet is so you can go with out going in your pants. You also need a Wheel to use a car,airplane,tranand jet to use a wheel. But a Toilet is better because you might not have any where to use the bathroom. Its true that you need a wheel but you always need a Toilet more.
