Sexist co-worker

Help with this model please.

C – Coworker answered my email
T – Don’t you delegate to me you sexist!
F – Anger/put down
A -I asked for his help on something that was supposed to be done before by both him and me individually
Was checking in to see what he had done and if he could share it with me on a joint project
He hadn’t done anything so he “delegated” it to me
Action of swearing.
Cooled out immediately and decided to…
Won’t answer email
R – I will do it myself and not ask again.
