The reason is because God creates human beings for mutual respect and appreciation. Because we should respect the work of others, even though we do not like. Same thing with your work sir,
and the reason we appreciate others so that the person does not feel his work is bad or ugly, and by appreciating the work of others we will certainly be appreciated by others sir, so it helps us to help each other and help each other.
so am I to you, and you to me.
sorry if my reply is a bit hard sir
