What is it?

Finally, home at last now I can go get the soft delicate thing. While small in size, it lets your head feel like a bottle floating on top of the ocean. This thing can come in any color or any design. The one that I have is a plain white but its cover varies from week to week. Every time you touch the thing an image of a nice cozy lodge with a warm fire is played in your head. I always end my day and start my morning with this fluffy item. Everybody probably has one but if not they are really missing out. Well it's time for me to be engulfed by the comforting thing so goodnight and sleep well.
