Who has a memory box? Well? You know. A box, full of MEMORIES. Like, receipts and train tickets and things.
I have a little bit of one, it's got some gig and football tickets in it. I used to have a much larger one, but I got rid of it as it was taking up space when I moved house.
I like nothing more than going to watch a gig, then getting home and putting the ticket into my memory box.
