Why Maple street neighbors suspicious of Les Goodman?

Oh, dude, so apparently the Maple street neighbors are side-eyeing Les Goodman because he's been watering his plants at midnight. I mean, who does that, right? Like, I get it, it's a bit weird, but hey, maybe he just likes to keep his plants hydrated in the moonlight. Can't blame a guy for wanting his begonias to thrive, right?
