We can easily be hurt or become angry when someone does something that doesn't fit with the way we feel we should be treated. We take things personally. I know I usually get reminded of this daily.
Someone leaves the cap off the toothpaste. Someone else doesn't clean up after themselves. Someone cuts you off in traffic. Blows their horn when you stop to let a pedestrian cross. Some days it can be a seemingly endless list of petty and major issues of disrespect.
What if it wasn't about us?
We take it personally because to us we are the center of the universe. Everything around us and interacting with us is personal. What if the other person doesn't even know we exist? When they blow their horn they don't know us from a hole in the ground. They are just acting out their frustrations with their personal world or acting absent mindedly from their needs.
It is when we take it personally that it causes suffering in us and reactive responses from feeling hurt to outright anger. When the cap is off the toothpaste just put it back on if that is what we want.
Nothing is personal even when they insult us. They are simply acting out their frustrations, anger, fear or issues of self-worth. Short of being a safety issue for ourselves do we want to join them in having a frustrating life or do we want something better for ourselves.
The choice is ours.
