1- We as human, an animal on two legs, are creatures who predict anything might be happened on the future: Maybe the toilet pipe is being taken when we are emptying our abdomen. At the sensitive time, we can not repair the problem, but we can use another toilet.
2-The picture show us, the human is a most loveed creature on the earth, and even when a lever wants to go to toilet the another lover go with him(her) to toilet if even he(she) has not toilet work!
3-“All human beings are born free and equal in dignity and rights." Therefore, any human has the right uses toilet when he(she) needs it! maybe I want to go to toilet at the same time that you will do it. What will happen at the time? Must I go to toilet or you?! I have the right go to toilet because I have to do it, but you need to do it, too. After this we do not have the such problem because we can go to toilet together. (Please note that at our times, we can not make two toilet in our homes becuase we have just a small apartment.)
The three interpretation show us the big fact: We live at the time that we can justify anything with our interpretation even if the thing be a disaster, like genocide! even in the name of human right!
