You're just being practical. You're thinking about your future. Someone around you might accuse you of being stingy on Monday or Tuesday, but perhaps they're just moody because they're not getting what they want. They're not being showered with cash. Wednesday, thankfully, your social interactions turn on how interesting your conversations are, not how much money is flying out of your pocket, and Thursday and Friday bring you further enjoyment on the intellectual front. A light debate? A reading at the library? Something like that would be good. The weekend is a blur of errands and details.
