I'm a firm believer in math & having just completed a statistical analysis of the course of my friendships over the period of X to X' that is, ie., since we met the numbers show that everyone who was my friend at point X, whom I introduced to you is no longer my friend, but now instead is a friend of yours To correlate my results I undertook fieldwork of a participant oberver nature I introduced myself to you as someone else then, when I wasn't around I asked you about me & I carefully noted your responses plotting them against the same answers when posed by me and this is the result Thought you were my friend / But I was wrong No one but myself to blame / So I blame you / Backstab! / Stabbed myself in the back
