It’s tempting to gloat when you overcome the competition.
Brag a little.
But the boot in.
But that doesn’t achieve much other than make you look like an ass, and potentially make an enemy-for-life.
Better to show magnanimity.
Show forgiveness for past transgressions.
You’ll look like the bigger person, and who knows, maybe the competition reappears later in life in a stronger position.
Better for you if the venom is less.
