Crazy Lady at Borders

This peculiar story begins with me studying at Borders. I like this specific Borders because everything seems spread out and wide and in view. So right when you walk into the store, all you see are books! So as I enter I heard toward the coffee section of the store with tables and chairs. I check out which tables are open and which is optimal for getting work done. I see a wide square table with no one there expect an empty chair, and I think, "Sweet!" So I settle down and lay open my massive math books and begin to work away. Then, maybe 20 minutes later this elderly Black women comes over and asks if I could switch tables with her so that she can do her "homework." Keep in mind all my math books are spread eagle. And as she makes her suggestion she points to a smaller open table about half the size of mine. I ponder for a second and try to figure out if I should oblige. I decide and I say, "No thanks, I'm going to stick with my table to do my homework." Then what comes next takes a few seconds for me to process because of the pure ridiculousness of it.

"That's Greed!"
"That's just so selfish, that's what it is!"
"This young man has no respect at all!"
...and continues for another few minutes with similar comments.

My flabber is gasted. Where the heck did this crazy old woman come from?! What the heck is she talking about?! She continues with her comments while I attempt to finish my homework but it's no use. I look around at some of the other people around me and they seem to be as in shock as I am. One gentleman says to me softly...."tell her to f*** off, finish your homework." For a moment I am comforted that at least one other person is as flustered as I am, and I am finally able to finish my homework.

I think back and it's find of funny but what a crazy situation. What a crazy lady. Where do these people come from?
