The context of the following conversation is Jan was going on a camping trip. she bought a sleeping bag from a store.:
Jan says I got the longest sleeping bag that they had so that my feet stay warm..
The friend responds I didn't realize sleeping bags come in different sizes..
Jan responds They do. With a longer sleeping bag I can put extra blankets inside..
The friend responds That is smart of you especially if you like lots of blankets..
Jan responds I do. I've gone camping with a standard size bag and was cold all night..
The friend responds Well you should be able to get 2 or 3 extra blankets in that long bag..
