"By Hurting Others, You are Hurting The Ones Closest To You."
"For Every Action There Is A Reaction"
last but not least...
"Any Man Can Wreek Revenge, A Real Man Can Forgive and Forget, And Get Over It."
I've heard the saying there is plenty of fish in the sea, which makes me think of the old saying from home.
"why go for the fish when you can score a shark"
meaning fuck the fish, get something better.
