sub this for that.
If we knew their story, we'd probably be more sad than angry. So, the next time we feel angry, try subbing sadness for the anger and see what happens. It's generally a more productive emotion. Sadness leads to vulnerability and empathy instead of violence and separation - like anger does.
Just swap out sadness for the anger. See what happens.
Then, be sad with those who are sad. Be happy with those who are happy. And leave the anger for better emotions.
