Pleasure through pain

What if some pleasures that are not bodily (memories, hopes, etc) that are listed in Book X still arise as pleasure only in their comparison to pain? The types I am discussing likely are not the types of pleasures that Aristotle would say would lead to Happiness and Contemplation but they still seems relevant to everyday life. The best way I could describe my thought is that pleasant memories only seem so pleasant because we are consciously or sub-consciously aware aware of all of our bad memories and that is why we cherish the memories(could be a way of deriving pleasure) that seem pleasurable not their self but because its not bad or painful. I believe we discussed this in class while reading The Republic but from a slightly different viewpoint and Book X of the Nic Ethics has reopened the question for me and I think it deserves some serious thought.
