"Why should I shut my mouth up?"

"Because some things are not meant to be said.
Because we don't want to hurt others
even when we're angry with them.
Because we might say things we'll soon regret.
Because we might break a friendship that's the best we ever had.
We shut up not because we accept defeat.
Not because we are less knowledgeable than them.
We shut up because we care about our relationship with them.
So calm yourself down and shut up."
