.Anyone can say "I'm sorry". The actions after are what makes the apology sincere, worthy and valuable. If you lie, cheat and steal and say "I'm sorry" and then do it again, you weren't really sorry. Take responsibility for your mistakes and wrong-doings by not being a repeat offender.
Do not tolerate being vilified. Distance yourself from those who seek to take underhanded jabs at you while maintaining their innocence. Such behavior barks of immaturity and a complete disregard for the feelings of others.
