Dearest Tim,

Chill out and read the following!
Humour or Humor is the ability or quality of people, objects, or situations to evoke feelings of amusement in other people. The term encompasses a form of entertainment or human communication which evokes such feelings, or which makes people laugh or feel happy. The origin of the term derives from the humoral medicine of the ancient Greeks, which stated that a mix of fluids known as humours (Greek: χυμός, chymos, literally: juice or sap, metaphorically: flavour) controlled human health and emotion.

A sense of humour is the ability to experience humour, a quality which all people share, although the extent to which an individual will personally find something humorous depends on a host of absolute and relative variables, including geographical location, culture, maturity, level of education, and context. For example, young children (of any background) particularly favour slapstick, such as Punch and Judy puppet shows. Satire may rely more on understanding the target of the humour, and thus tends to appeal to more mature audiences.

I have a mental picture of you in my head wearing this.....
