we should establish a spectrum of items that you would touch with your tongue, beginning with items you would definitely touch (eg: a toothbrush, a lollipop, the bowl after mixing cake) and ending with items that nobody could never even possibly touch (eg: the back of your own head, a unicorn, the surface of another planet). can you name ten items and number them 1 to 10 to begin the spectrum?
numbering things off requires too much thought, all I want is pizza.
It’s just easier to list some things I would not; Some one else’s toothbrush, seafood and “off” food stuffs, animals, dead things (bar the edible meaty bits), 99.99% of other people or their stuff and surfaces that come into contact with many people. :\
