Memories are like a big pile of carpets, I keep them piled up in one big pile in my head and don’t pay much attention to them separately, but if I want to, I can get back in and walk on them and remember. I’m not really there, not like an elf might be, of course. It’s just that if I remember being sad or angry or chagrined, a little of that feeling comes back. And the same goes for happy, of course, though I can easily wear out the happy memories by thinking about them too much. If I do, when I’m old all the bad memories will still be sharp, because of pushing them away, but all the good ones will be worn out.
