My memory is very fragile. I can rewatch an episode of a show that I've literally seen last week and I won't remember that I've already seen it. I can reread books and reexperience them entirely. Some things do stick in my brain better than others, or I might recognize things about halfway in, but in general it's no good. Along with this I also seem to have a terrible recollection of faces, so watching TV with me is always a challenge. My colleagues are now telling me things like "this is the same guy we saw at the family dinner earlier", to help me understand the context of things. It's really quite interesting, and at least I do remember important things like who I am, what I do and who the important people in my life are, but it's definitely a challenge.
