Stop and pause
If someone acts irrationally, they get in your way or otherwise put you off, intentionally or otherwise, stop and pause.
And that’s it.
No need to react. No need to stoop to their level. No need to get involved.
Stopping and pausing is the first step on the way to acceptance. It’s the first thing we do when things don’t feel right.
Don’t partake. Don’t react. Just accept and move on.
