But I have that within which passeth show;
These but the trappings and the suits of woe.

– William Shakespeare

Hamlet, Act 1, Scene 2. Hamlet makes this reply when his mother asks him why he still seems to be upset about his father’s death. He says he doesn’t just seem to be in mourning, but he has feelings inside him that surpass what others can see on the outside with his black mourning clothes.
