I had a guy on a skateboard jumping on roofs of houses.
I used to 'race' droplets of water on my car window.
I still work out words on car registrations, and count stairs as I go up/down them, and paving slabs between driveways. That one comes from my paper round as a kid.
I still work out weird counting methods. I have to make everything equal 1. If there's 4 things in front of me, like buttons on a remote, there's four 'things' and 5 gaps. That adds up to 9, if there were 9 buttons there's 10 gaps. That adds up to 19. 9+1 = 10. 1+0 = 1.
Yes, I'm very strange.
