Eating habits are supremely personal and can be very strange. First of all, it's a weird concept that has somehow been normalized because of "survival" or whatever. Think about it, we put strange globs in our mouths, chew them down with our saliva and then it gives us invisible "energy" that helps us move our bodies and function?! EATING IS WEIRD AS HELL when you think about it
As with any ritual we perform every day, people have very specific and sometimes nonsensical rules they make for meal time. For some people, the sight of different food groups touching on a plate can launch an emotional spiral, while others actively dip french fries in their milk shakes. No matter how weird you think your relationship to food is, there is undoubtedly someone with a stranger tale yet.
