Analyzing the cause of anger works

I was almost gonna get miffed with a callous service station person .. Then after cursing them for being unprofessional and inefficient and not really wanting to work.. suddenly is realized and talked to myself aloud,
"" these are people that are stuck up in a service center for televisions..they just repair stuff. It is not like they invent stuff each day.. they just repair stuff.. Maybe the job is not motivating enough.. perhaps they just pay them the same , no matter how fast they repair televisions.. Maybe they wont get a bonus even if they do swift service..Ya know.. Maybe they feel their job sucks.. Maybe they feel unimportant by way of their work, which is why they harrass the customers to make themselves feel important" and suddenly i started realizing that i nailed the reason for their inefficient callous behavious.. the real reason why they do that, made them pity them more than i could get angry with them..
There ya goo..shitty people are shitty for a reason.. It is worth the time to find reason to pity them and not get angry.. coz pity is not harmful to the body. while if i get angry , i hurt myself
