I too have the tendency to get mad at little things.  I remind myself that if I am upset because of something on the level of having to replace color cartridges, my life is so good.  Maybe too good

During the Christmas UPS screw-up, with Congress threatening action against UPS for screwing up some deliveries, I thought that life is so good for us if it is a national scandal that someone did not get his Cristmas present on time and it came the 26th instead of the 24th.  

I once met a refugee from the Sudan who had a family member killed by a lion when they were crossing the desert to get to safety from warning tribes.  On a bad day he had to change printer cartridges from a NAZI company.

Years ago, I had a friend with a disease that slowly makes it impossible to do anything physically.  I used to go to her house, carry her to my car, carry her into the cafe we used to go to so she could see friends.  It was getting to the point where she could not lift her coffee cup and had to use a straw.  

One day I told her, "Monica, some people have terrible luck. You don't know how bad it is for some people.  My AFT dance partner is leaving L.A. to go home to Ohio and I have to find a new dance partner."

Luckily Monica had  a sense of humor.  She said she felt bad for me
