That’s correct, Skrit. We here have NEVER witnessed anything even remotely resembling sarcasm emitted from that chirpie little beak of yours. I, for one, will go on record as saying you are a prime example of rock-steady sincerity. You are a pillar (pillow?) of genuine heartfelt empathy. A virtuoso of earnest candor. And as a fellow member who also refrains from the use of sarcasm, I applaud your mighty efforts to remain forthright in the face of logic-lacking lollygaggers.

Geeez… Get a clue already.
