Why can't I sit down?

I do try to take a break and sit with the girls in the living room. However, how can I sit down when I come in and see this:

I have been trying to explain to Celie that her stickers need to go INTO her sticker books, but she would rather have them all out for display. She plays with the stickers like puppets. It is actually pretty creative, if you ask me, but it is frustrating to A) not be able to sit down on the couch and B) stepping on the stickers that have lost their "stick" and have ended up on the floor, but seem to have enough "stick" to cling to the bottom of your feet. ARGHhhhhh!! (Those are the ones that mysteriously disappear).
