Nothing makes sense on Monday. Everyone's acting completely absurd. There's a strong chance no one means anything by it, and trying to decipher motives behind the madness will only drive you into further confusion. So, relax. Take everything with a grain of salt. If it really starts to bug you, find a good friend (someone steady and normal-seeming) to vent to, but chances are by the end of the week you'll see that none of it had anything to do with you anyway. Friday or Saturday, you are on the verge of making a purchase when you decide to shop around a bit more. Wise move.
