I’ve got one to add to the list!
“Remember a favorite book from elementary school and fantasize about being able to go back to the (now demolished) library where you can still remember the approximate area where it was shelved, in order to check it out yet again.”
True story! I must have been in sixth grade when I read that book and I still remember how much I loved it and how much I laughed while reading it. If I could remember the title (or the author) I would search for it on Google so I could read it again!
