I can just imagine the turmoil that a misplaced sticker would cause in the mind of a feeble person. Nagging doubts would creep into their mind all through the day, inducing a feeling of unrest.
I can see now why the original poster would seek further opinions on the best place to put the sticker, they can draw up a chart of sticker placements, then over a period of time, and after much consideration, place it in the most popular location.
One can only feel sorry for people who rush into placing their stickers, only to have to suffer the mental torture of peeling the sticker off, and sticking it somewhere else, oh the shame !
