"What is it?" he asked, as she poured him a glass.
"Just try it."
He took a mouthful of the liquid, and his eyes widened. He froze a moment, then carefully, painfully swallowed.
"What?" he gasped.
"Flavored iced tea," she answered, a smirk playing about her lips.
Hatter seriously and deliberately set the glass down, and pushed it as far away from him as he could reach. "Alice, my love, I'm very sorry," he said, his voice full of regret.
"I'm afraid your world had just proven to be madder than Wonderland ever could be!"
AN – Personally I rather like flavored Ice Tea, but I imagine Hatter would be horrified by it.
