Mrs. Snowden tells the kids that T = True, H = Helpful, N = Necessary,
and K = Kind. If what you're about to say isn't any of these things, she
tells them, you shouldn't say it. Later that day, when Tyaja is about to
criticize her friend Dhavi's new haircut, she is stopped by four little
elves sporting the letters T, H, N, and K, who reinforce Ms. Snowden's
lesson and remind Tyaja how friends should treat friends. Tyaja learns
that she is the "I" in THiNK!
