Sounds T-Shirt

Sounds good. Sounds fine. Sounds like a plan.

SOUNDS is the most agreeable word in English and the least committal. It says yes without promising anything, and does it so pleasantly that nobody ever notices. Enthusiasm, at exactly the required minimum.

Why "SOUNDS"? Six letters holding noises, seems, agreed and fine by me. SOUNDS is how people say yes when they have not fully decided.
