It is written as a description of the feelings of a man who is so in love with a woman that hearing her say that 'she hates' something immediately creates a fear that she is referring to him.
It is also the Shakespeare sonnet which uses the fewest letters. It forms part of the Dark Lady sequence of sonnets and is the only one written not in iambic pentameter, but instead tetrameter. Sonnet 145 is one of Shakespeare's sonnets.
