So - why did you get offended? And no, I don't mean, "what did that mean, bad person do that annoyed you" -- I mean, why did you get offended? Why were you set off end by this other person's actions - why were you knocked off balance?
Just something to think about -- why did you let your self get knocked over? If you have been "off ended" by someone... why aren't you standing back up, dusting yourself off, and getting on with life? If someone has "up set" you... why are you remaining up set instead of standing back up and doing what you ought to be doing?
Being offended, being upset simply means you are abbrogating responsibility for your own actions, feelings, or responsibilities.
You are you. Live the life you have been give to live -- love your neighbors, even your enemies. Show them kindness. When reviled, do not revile in kind. Explain things in the kindest way. Bear one another's burdens, including when that person is in and of themselves a burden.
But dust yourself off, stand back up, and do not let anyone offend you.
For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery. - Galatians 5:1
Be watchful, stand firm in the faith, act like men, be strong. Let all that you do be done in love. - 1 Corinthians 16:13-14
You know -- don't let yourself be offended. It's never worth it.
