What is Courage?

My son has been having some issues with an older/bigger/meaner/obnoxious (what i would call a BULLY) kid at school and we’ve been working with him/his teacher/the principal about it. Tonight he asked me to give him a few lessons in courage. It just breaks my heart to hear him ask about how to be brave. Some things we discussed tonight include how people who do brave or courageous things are sometimes still scared; that sometimes kids act out like this because they want negative attention/any attention but don’t know how to get it in other ways; talked about worst-case-scenarios (ok let’s say Boy X does punch you… then what); dad is going to show him some self-defense stuff (he’s a police officer), how to block punches, etc.

My inner ‘mama bear’ just wants him to clobber the guy…

Now that he is in bed for the night I just wonder what else we can tell him/teach him… Your thoughts or experiences?
