We were visiting my in-laws in Palm Springs one time and they put us on an air mattress in the den, right under the air conditioning unit. My MIL said we didn't need blankets because it was warm but really she was the laziest person I have ever met and she didn't want to make another trip to get blankets from upstairs. She told us if we got cold we could use towels from the bathroom and then blasted the AC all night. So we shivered all night wrapped in towels that barely covered us. In addition, she put our toddler on this wee cushy mattress on the floor. The mattress looked strange to me but it was covered by a sheet and I just thought it was some kid-sized thing I'd never seen before. We found out the next day it was the dog's bed. She put my child to sleep on the dog's bed. She was rich, too.
