I remember finding the poem difficult first time I read it and rereading it now I remember that I had no idea how the hand that mocked them and the heart that fed followed from what had just been said Because I read survive as merely saying that the passions were still visible rather than saying the passions outlive something I think a lot of people could make a similar mistake on early reads so while perhaps I was the stupidest person in my English class I think there are enough people at least as stupid as I to warrant keeping the advice there
