Consider the following conversation with a geriatric neighbour:
Self: I'm so happy they finally put these new benches in the park.
Geriatric Neighbour: Yes, well, it's only a matter of time until horrible, dirty, homeless people come set up camp on them.
S: You know, in the States all the new benches have uncomfortable dividers to keep people from lying down on them. And in England they even put spikes to keep homeless people away.
GN: How awful! The homeless people like to sleep outside when it's warm out, but the ground is all wet! No, no, no, better this way...
