I do not know the man I should avoid So soon as that spare Cassius. He reads much, He is a great observer, and he looks Quite through the deeds of men. He loves no plays As thou dost, Anthony; he heard no music; Seldom he smiles, and smiles in such a sort As if he mocked himself and scorned his spirit That could be moved to smile at anything. Such men as he be never at heart's ease Whiles they behold a greater than themselves, And therefore are they very dangerous.
