Cherished Memories

While watching the Harry Potter films, my sister and I often point out which abilities or talents from the films we wish that we had. One thing that I have wished I could do is pick specific memories from my mind and store them, never to fade or diminish with time, as some of the wizards do (particularly in Harry Potter and the Half-Blood Prince). Then the thought occurred to me, if I had this ability, which memories would I desire to keep? Which memories do I consider valuable enough that I would wish to save them forever? Even knowing that it is impossible to do so in reality, it is an interesting question to consider, because it reveals in a roundabout way which memories you cherish the most or consider to be most important. Think about it. Which memories would you choose?
