When I was growing up, my mother had a set of plastic bowls that were pretty much generally just for me to use (I was an only child). Identical except for color, the bowls were pink, brown, and yellow. They would get stacked in the cupboard in a random order, and I believed that whatever color bowl I had for my cereal that morning, that was the kind of day I would have. If the bowl were pink, I would have a good day, brown meant a bad day, and yellow was just neutral. I often skipped the brown bowls, preferring to pull out the next pink one.
