Not even a little bit.
I don’t like lying.
You know . . . I've been reading this thread and following all the comments to the above response. Thought about it for a while before I responded.
I think there are two ways that this truth-telling response can be delivered.
1. With a scowl, a vigorous shake of the head and a bit of anger which would present a "now go away" attitude. This, I think, would be rude.
2. Or with a ha-ha joking attitude. This delivery, I think, would lighten the mood while allowing someone to speak the truth. Plus the recipient of the comment would probably brush it off as in "She's such a kidder."
