I want to draw your attention to the incorrect interpretation by people of their innate instincts. Why when others badly we laugh, but we are taught that it is bad and so do not right?
BUT why it is not right, if we are funny. We do not do it on purpose, it happens naturally. But to force others to act is unnatural. Therefore, the rules when it is allowed to laugh, and when there is no vaccination with the help of force even from childhood.
Cases from life:
Someone slipped and fell - we are having fun ... there is a truth exception to this rule. The forty-year-old farmer Elia, a convinced bachelor, is characterized by a rude character and a hostile attitude toward the ladies. ("The Taming of the Shrew" (Italian Il Bisbetico domato) - an Italian comedy in 1980)
someone looks like a freak - we have fun ...
somebody got dirty - it's fun ...
someone hurts - we have fun ...
and so you can continue without of course, watch what makes you laugh.
You will never laugh when someone is good or someone is happy ...
probably the conservation law works here according to the principle - if it's good for us, then to someone it should be bad.
laughter prolongs our life! - but at the expense of the lives of others.
Yes, all comedians, all of their texts are built on the humiliation of others and ridding of problems or troubles.
And laughter and Sin
Something like this.
