Don’t give people a way to get around your boundaries. They'll just learn that there is a way to violate them, without repercussion and seek out more boundaries to push back.
One of the ships I was posted had to have the entire crew practice marching before a parade for freedom of the city. But we had come off of deployment not long ago.
If I pas in front because they were creeping into the crosswalk I purposely make eye contact while I do my thing.
I want to see the shame in their eyes.
