There is an old-aged game that people like to play nowadays, called "as soon as you take things seriously, you lose".
Ok, perhaps starting from today I should learn to get used to it gradually.
We can't stop ourselves from getting angry, but we can learn what to do when we are angry.
Just tell yourself, why so serious? why bother so much? Come'on it's just a joke! Let's give a smile and act like you don't even care at all:)
