A white fluffy blankie that is never white and is always so filthy that we call it her Immunity Blanket because it would be riddled with germs. I tell people it's because she won't let us wash it but really it's because I forget

I still have a habit I had as a kid and like to untuck the sheet, loop the edge around my thumb and rub my thumb in and out. I used to call it my tickly thing. Can't quite believe I just confessed to that one!
