Why is it that you can go for years and years without noticing something, then suddenly you see it in a completely different light and it changes your view forever?
I've just noticed that the adverts on the side of London buses are made up of four clearly seperate sections with clear plastic dividers inbetween, and are not as I previous thought just one big advert.
Okay so it's not exactly life changing but I can't not see the divides now. (Ooo a double negative)
