[Tip]

I don't know that they lie. They may exaggerate to get across how strongly they feel, or it may actually be that they perceive things in a certain way.

We can see how people perceive things to be completely the opposite way from others often enough on these forums - doesn't mean anyone is lying.

I do think it's possible that Dee feels cornered when Gary starts questioning her reasons for nominating him, I think she does feel a bit threatened by him (psychologically) when he is out to "persuade" her that she is wrong.

A similar explanation could be applied to the "interruption" thing when people were already frustrated by having to stop their conversations with others to converse with Gary. It could all be in the perception.
