I once asked my mother that if people grew bigger as they got older, what happened to other things, like the table, or my toys... she told me that, obviously, they shrunk. So for a long time I believed that living things grew bigger over time and inanimate objects got smaller.... easy to believe since I kept outgrowing all my clothes.
