The Office V

Have you ever encountered those people who have jars of candy or bowls of chocolate at their desks in their cubicles?
What the hell is up with that?
They're obviously not going to eat all of it, since they would not be able to fit into the chair behind their desk. So one must assume it is meant as some sort of offering for the people around them. One must therefore also question why it is they feel they need to feed the sugar habits and sweet-tooth of their office-mates?
Is it because the were unpopular in high-school/college and attempt to make friends by offering candy? Will no one like them or come talk to them unless they can, at the same time, bite into a Mars bar or a Tootsie Roll?
Is it because they have a sinister hidden plot to make theor colleagues fat so as to feel better about their own lack of positive self image (just for the record, this is why I would do it if I were to do it).
I dunno but it strikes me as unnatural and evil. As it is the cookie jar in the break room is bad enough.
