But here's an interesting fact about being offended: it's a choice, just like most emotional responses.
You can choose not to be offended. That doesn't mean you always should choose that path but most of the time it is the better choice.
If someone cuts you off in traffic on the way to work, you can A) be mad at the person, try to retaliate, and go to work in a bad mood or you can B) forget about it and not waste your emotional energy on a bad driver you will probably never meet.
Choosing to be or not be offended is similar.
