Sarcasm is an adjusted stress reaction.

I went to public schools long enough ago that girls (and female teachers) were required to wear dresses or skirts. The year (in the 1970s) that pant suits became fashionable, the high school Physics teacher received one for Christmas. She wore it to school in January. The administration agreed that that was a formal enough look, so the rule was changed to allow pant suits. That broke the dam - by then end of the school year, girls were wearing jeans.
