To further confuse things, even the meaning of "friend" is subject to scrutiny. "Friend" can be used to greet a complete stranger, it can mean someone of the same sex that is an extremely close friend, and it can even be used to describe a man and a woman in love. In the same respect, lover can be meant to have sexual connotations or just imply a strong platonic friendship. Hammond states, "The words 'love', 'lover', and 'friend' in the Sonnets have no single or unambiguous meanings, but are continually being redefined, refelt, reimagined." He also states, "Sometimes indications of sexual desire are present not in the form of metaphor or simile, but as a cross-hatching of sexually charged vocabulary across the surface of a poem whose attention seems to lie elsewhere."
