Describe a time when someone offended you with their words.

 A time when someone offended me with their words was when they called me failure. I was casually minding my own business and all of a sudden someone I don't know walks up to me and tells me that many things. I was trying to understand who this person is because I don't know him. And all of a sudden he starts saying things that weren't true and when he told me that I was a failure I got so offended  after those words we had said.
