Camping mattress on the floor is dumb, especially considering how many "receipts" there are for his bedframe begging, and photo evidence of it existing plus his actual mattresses (mattress and box springs?) on top.
However, once again I speak as an adult first, and then a woman: put sheets on your mattress, you horrible grease beast. Periodically launder the sheets and replace them, to keep the mattress and blankets clean. Lou, the creature of Walmart, knows a twin sheet set does not cost much--and I suspect his nephew is in a twin bed, too, so he could easily borrow a set of sheets.
I wonder whether those trans-colored programming socks were staged. Lou has a certain low cunning, and might have decided he needed some proof of his trans identity. On the other hand, if any thought were given to how that picture would look, why wouldn't he straighten up a little, pull the blanket up, hide the several hundred dollars' worth of electronics including a handheld gaming system.
Point of order: people do use their cell phones as alarms. Probably not Lou, but lots of people do.
I use an alarm clock because I am old and stodgy, but also so I don't fumble my phone out of my sleep-numb hands first thing in the morning, so I can turn my phone off/set DND without worrying I messed up, and because the alarm clock is also the bedroom clock. It will be interesting to see if alarm clocks become harder to find in the coming decades, though, as the culture cycles.
