Sleeping Bag

My roommate and I spent all day at the vet with one of my cats. We came home to crash on the couches for a few minutes. My dad was watching TV and was very excited to show us something.

Dad: I was going through my crap.
Me: Uh huh.
Dad: I found that. (Points to rolled up sleeping bag) You can use it if you ever want to go to an outside event.
Me: An outside event? Like in the winter?
Dad: (Gets up and starts to unroll it) Yeah. I slept in this thing in 40 degree weather. See, you just unroll it and climb in.
Me: Ok.
Dad: It's made of goose down...and this other stuff. (Talking to my roommate, Cori) Cori, you can use it, too. It would be good for an outside event.
Cori: So, it's like a cocoon?
Dad: Yes, like a cocoon.
