Two things: 1. "sin()" uous - like a sine wave, twisting and winding <br> 2. "sin"uous - a person who commits sins (by being dishonest).
SINuous...one who commits sins is NOT MORALLY HONEST
sign "you and us" on the card and they will be really confused
SINUOUS and TORTUOUS which are rhyming words refer to something that is full of twists and turns.
