It is 78F in my apartment right now with the air conditioner running.

I am in the same room as the air conditioner, it's right behind me. It's blowing cold air. I'm on the second floor of an apartment building, the outside is brick and the roof is a fresh flat rubber roof. My apartment in particular sees 100% of the day's sunlight. It has been 90F and sunny for the last 2 days. The air conditioner kept it at 73F most of the day, but when the sun goes down it only gets hotter in here. You see, the bricks absorb the heat all day, then discharge it inward at night. It doesn't dissipate outward, only inward it seems. My outside walls are warm. I'm sitting still, in basketball shorts and a tshirt with the sleeves cut off, and I am sweating. We have a second portable air conditioner, but the compressor stopped running at the end of last summer. Now the fucker doesn't even power on. It's well out of warranty. Fuck me, I'm getting desperate.
