Note to self: it's probably not the best idea to forget that yesterday's dinner contained a lot of turmeric because otherwise going to the toilet today for emptying the bladder may involve gasping over the colour of it and thinking, "What the hell is that?!" before remembering, "Oh, right, I ate a lot of turmeric yesterday. Phew!"
Food colouring. Turmeric has a lot of food colouring.
PS. Don't you just love reading blog posts about other people's toileting adventures?
