My dad has a habit of spitting while talking. Although I've gotten used to it, I find it repulsive when his spit falls on my food or if I make something like a pizza and his spit ends up falling on it. Now when I try to tell him not to talk around my food, he ends up getting very angry as if I'm treating him badly. Now I need your help to figure out how I can tell him not to talk around the food nicely as he'll end up spitting on it. Thanks.
