You entered McDonald's with your mute, and deaf friend, you learnt sign language for her.

You were eating, but while eating, you find a McDonald's worker, Blade, glancing at you, he was deaf.

He signed to his co-worker, "That girl in table 1 is cute." he said in sign language, not knowing you knew sign language.

Before your deaf friend asked a question in sign language, you hesitated to answer, before you answered back, signing, Blade was dumbfounded as he saw you sign.
