The most insulting thing anyone has ever said to you was...

A junior high teacher once asked me to stay after class. As soon as all the other students had left the room, she said to me with a very condescending smile “I just wanted to tell you that soap and water make a person smell wonderful.”

Ugh! The nerve of that *^!%+ I actually asked multiple people throughout the day to smell me. None reported anything amiss. I felt so… wronged, haha.

Can you relate a similar story where someone came out of left field with something highly insulting, that had absolutely no merit?
