"This week people in our community confronted me about my lifetime of
not understanding emotions. My flippant attacks in emails have been
both unprofessional and uncalled for. Especially at times when I made
it personal. In my quest for a better patch, this made sense to me.
I know now this was not OK and I am truly sorry."
