The monotony of life can sometimes make us dull or tired.
So, take time every day to make some fun for yourself.
I don't mean land yourself in jail or the newspapers for something off the wall.
The best fun is the fun only you are having but that others notice and don't know what the joke is.
I do this with certain people I have to deal with.
There is one person who will say something that honestly you don't know if it's a question, a statement or an accusation. Yet I know she wants a response of some kind so I just look at her. My face impassive. A bit blank. And the fun is when she honest to God shakes her head slightly and blinks.
I've been trying to find the humor in things that would normally make me angry. And it's working. Especially when dealing with nasty people. If you respond in the opposite way to what they expect or hope you will it's the funniest thing to see their face.
