It’s kinda hard to describe, but I’ll give it a shot.
Let’s say I have a bag of Skittles. I dump the bag out and separate the flavors. I find I have 15 orange, 12 grape, 12 strawberry, 9 lemon, and 8 green.
Green is the lowest number, so I make 5 piles of each flavor, 8 in each pile. This leaves me 7 orange, 4 grape, 4 strawberry, and 1 lemon.
Lemon is now the lowest number, so I separate 1 from each of the remaining 4 colors and set the aside in their own little piles. Now I have 6 orange, 3 grape, and 3 strawberry.
I separate the remaining flavors into piles of 3, leaving me with 3 orange.
So I eat the 3 leftover orange Skittles first. Then I go backwards in the order I made the piles: The piles of 3 grape, strawberry, and orange. Then the set of lemon, orange, grape, and strawberry. And finally the piles of 8 that I had originally separated.
If someone comes along and takes a Skittle or two form any of them piles, I rearrange them again. It’s sad I know, but this is the only thing I do this about. M&M, Reeses Pieces, whatever I eat all jumbled up, but Skittles have to be separated.
My BiL saw me do this once and that upcoming Christmas bought me a one-pound bag of Skittles just to watch me separate them.
