Why Do People Do What They Do

Why do people think that because you have more than one of something, that they are entitled to the other ones. For example, one day, at school, I went to lunch, as usual, while waiting in line to buy food I had a burst of hunger for six Swiss Rolls and only six Swiss Rolls. After buying them I proceeded to my table where I sit everyday and as I was getting settled in, using one arm to pull a chair to the table because my other arm was occupied holding my six Swiss Rolls, I began to get attention from my friends who were looking at my Swiss Rolls with wide eyes, and licking their lips wanting one of them. I sat down and said, "What are you guys looking at?" One of them replied, " How many Swiss Rolls do you have?" " Oh, about six," I  said. And then somone asked me if they could have one and when I said no she said, "But you have so many, you don't need all of them." And that's when I  got angry... Why do you think I bought all of them, so that I could just give them away, NO! I bought them so that I could eat them! I f you want a Swiss Roll so badly go buy them yourself! Just because I have more than one of something doesn't mean I don't want it. It means that I want more than one because one isn't good enough! And it seems to be like that all the time at my school, " If you have more than one of anything here at school you are obligated to share." I don't know who came up with that policy, I guess I didn't get the memo, but I'm going to try everything to get that out of people's heads.
