If what you are trying to prove is true, then you don't need to exaggerate anything; you just need to be honest.If you don't like the example, deal with it. Exaggerations are meant to be just that: Exaggerated. You blew this out of proportion, AND made it personal, and that went beyond the line.
The fact that you need a story to be relatively true to even get a point proven to you is beyond me.
