I was out with a good friend a few days ago and, in conversation, she recounted a memory from a holiday she had 30 years ago - a beautiful beach and wildlife encounter - in a way that made it sound like it happened last week - with names of the beach, details of the weather etc. It struck me that she does this quite often, but I struggle to respond in kind because all my own similar memories of beautiful holidays in the distant past are so much more vague. Is her memory particularly good, or is mine particularly bad? Or is it just that memories stay with you longer if you regularly recount them? (This particular friend is also very good at pub quizzes, so I think she does have a very good memory).
