Since my childhood I am still living alone because of this problem i.e food sharing problem with my own friends.
Suppose if I went to party, friends are also invited. They putting their hands in my plate and eat it, which I really don't like. I am ready to share food, but putting their hands directly into my plate is a major problem for me. Sometimes they put their food into my plate which I feel is seriously disgusting. Actually I don't eat already consumed/used food.
How to deal with this type of food eating friends?
