If a balloon is an object, then a reference is the string attached to it A reference (string) is not the object (balloon), but it connects the user (person) to the object (balloon) object reference
A null reference is a reference to nothing This is a string, without a balloon on the other end
If you both have the same balloon, then the other person can change your balloon without your permission
If you don't want this to happen, give them a copy of your balloon instead of the original
