I’m with you, the story actually warmed my heart when I read what the waitress did. We’re always going to have a**holes out there, but as long as the good people outnumber the bad, we’re gonna be all right.
As I told my kids when they were growing up, being bullied says more about the person doing it than it does about you – wear it as a badge of honor that you didn’t get goaded into matching their bad behavior and took the high road. If anything, it raises your stature!
