Hello Sleipnir,

Being bothered by this shows you have compassion. But, compassion without wisdom makes for a faulty combination.
Can you control the behavior of others? Can you fight stupid people?
If you want to insert yourself into their situation then that is up to you?
If you want the yelling to stop then you can make that request?
If the yelling bothers you then you can put on headphones?

For me, Take a deep breath and try to mind my own business.
Can’t make another stop the yelling or change their behavior.
Can’t stop the other person from requesting orange juice.
Can request for peace and quiet but that brings up another contention.
When there is peace inside of me then I can share that peace with those around me.

Just need the wisdom to go with the compassion to make changes in my life that bring about better life.
Hope you can find that peace inside yourself

Tommy
