Dear people with functioning A/C units in their vehicles: please do NOT park in the shade. You don't need it. Really, you don't. When you take a shady spot, you force those of us with no A/C to park in the sun, thus turning our cars into literal ovens. We should not have to ride home in a baking hot car after grocery shopping just because YOU don't want to wait a full 5 seconds before getting blasted with the arctic blizzard your gloriously life-saving A/C provides. Meanwhile we're rolling all four windows down and sticking our sweaty heads out for that precious wind only a car in motion can create. Just FYI, that wind is still just sweltering summer air, but we take what we can get.
This has been a public service announcement from yours truly.
