Never do a single thing in the anticipation to prove something to someone who has hurt you. If someone has hurt or offended you (whoever that person may be), never perform anything or strive for anything in your life with the mind of proving something to that someone/ to those people. May nothing that you do be done with any thought of them in mind. There is nothing that needs to be proven.
