I will take responsibility for my actions and confront the issue (in as gentle a way as possible). If I've offended someone I'll apologize...If they've offended me I will try to look at their perspective with compassion (which is sometimes hard to do)...
Life is too short to spend it hurting others or feeling hurt. IMO kindness always wins...Although, we're only human and apt to make mistakes, be easy on yourself and others, no one's perfect afterall.
A lot of times pride gets in the way, which usually causes more harm than good. I feel that another person's feelings are more important than my hypothetical wounded ego --let it go and move forward if you can.
