Hi, No you can't get mono in the ways you described. You have to eat or drink after a person using their utensils or glass. It is only transmitted through an object that is moist, for example with that person's saliva. So from what you describe you don't have a possibility of getting it. Also, most people have been exposed to the EBV virus (that causes mono) by the time they are an adult so you probably already have antibodies to it anyway.
