No laundry lines, no tan lines

So we use our roof for hanging laundry. With the population of People Who Begin with P growing, the laundry expands exponentially. So the laundry lines outside the window aren't close to enough. Conveniently however, and unconventionally for our part of Stepford, the roof here is still common property and it has four really nice big laundry lines on it.
When we first moved here, there was one other family ... older couple I guess ... who also hung their laundry there, but for four or five years now, we have had the laundry lines and the roof to ourselves.
We now have new next door neighbors. A med student and his girlfriend.
They don't need to hang laundry.
How do I know this about our new neighbors? Because when they aren't planning on being home, they ask their parents to drop their clean laundry off with us.
Her mom drops her laundry off mornings, my guess is once a week. His mom drops his laundry off on Sunday evenings. Sometimes he's here, sometimes he isn't. He doesn't even ask us anymore. He already knows we accept laundry deliveries at all times of day or night.
So anyway, back up to the roof. We've been hanging our laundry there by ourselves for four or five years already. We sorta - but not quite - feel like it's our roof. We go up and down pretty regularly. At least one load a day and three on Fridays for towels and sheets. Just us and our laundry and Puppy who likes to do a lap or two at high speed up there before she takes herself back downstairs and bangs on the door with her tail to get let back inside. We never see anyone else. Us - Parents of P's, Puppy, and sometimes Peach who likes to hand clothespins to the laundry hangers.
Only this week, I met someone on the roof when I went up with the laundry. Remember the Girl Next Door? The one who doesn't need laundry lines because Mom does her laundry? Well she's getting her money's worth out of the roof too. She's sunbathing up there.
Yep. I want to grow up her. No laundry, no laundry lines, no tan lines.
