Do you have any Zen that helps you?

Do you have any Zen that helps? 

This is a little Zen thing I was taught on a business course which helps at times and it doesn't have to be just anger.

A Zen Master (ZM) was in a field with students, an Angry Man (AM) came up to them and was being very angry to the ZM. 

ZM: (to his students) If someone has a gift for you, but you do not take it, who does it belong to?

Student: The person giving it.

ZM: (to AM) Sir, I do not wish to take your anger. 

Just leave them to stew in it, don't let them pass it onto you and leave you with it.
