I realized that too. Many people find it weird to talk about poop. They feel so ashamed to say that they went to the toilet or latrine and released poop. Poop is associated with dirt because it comes from the body as the food that was not digested. So it is taken as dirty things coming from a human body. Moreover, poop has a bad oduor that human beings hate. So when you talk about it, people start imagining that bad smell that is associated with it. Also, I think people find it weird to talk about it since when one goes to the toilet to release it, they do it individually and don't want to be seen by anyone while doing it. So poop is just something private. Poop is something so natural and biologically good. People should not find it weird talking about it. But you know, people do not just change things all over sudden so we should just let it be. Avoid talking about it when people are seated for a meal, that is an advice to take to the bank.
