Here's an idea, and I'm just brainstorming here, but let's say your character just moved into his new place. Perhaps he's on the phone with his mother, trying to describe it to her. If you choose the "same setting, different viewpoint" exercises later, you could either have mom show up later and give the new description in her own words on the phone to dad (he's crazy! the place is a pigsty and something stinks under the bathroom sink), or you could have your protagonist describe it to someone else - say, his buddy - who would care about different aspects of the setting. Mom wants to know if it's clean and warm, if the hot water works, if it smells lemony-fresh. Buddy wants to know if there's a big-screen TV and beer, and whether there's a place to build a fire, but he doesn't care that something is rotting behind the plumbing. Your protagonist might adjust his descriptions to better satisfy the curiosities of two different listeners.

In general, the idea is to have your character describe the setting, in detail, to someone who is not present in the setting. Does that help?

Cheers,
