When I was five, we sang a hymn in the school hall every Friday and one of the hymns said "tell me who made the world" - I thought 'tellmewho' was the name of a person and that this person made the world, lol! Later on I thought Tellmewho was another name for God... I was seven when I realised "tell me who" is three separate words!!
