From Bag Lady to Hoarder

Scarlett's latest thing is piling all her stuff on the couch. Some nights, it's so covered with her stuff that we can't even sit on the couch. I don't know why she does that but she likes to take everything she cares about that day and put them on the couch. Part of it is to keep them from her brother but really? Do you need to put all your trinkets, knick-knacks, paper notes, stuffed animals, and other junk on the couch?
