I would address my feelings in letter as to how it makes u feel as a human being, everything else aside regardless what the event lesson or act is, we all deserve to interact in peace as long as we aren't threatening.... your desire to kill is a product of you holding on to the cruel hurtful words , release them back to the offender...but tell them what they are doing and how it effects you....it's your right...then ad footnote.... telling them you choose as a person not to take that form of abuse.
