My headboard is up against a wall, and also where my pillow is, so I can't sleep inverted like that either. I can't sleep with just one flat pillow, I need another to prop it up. But without the wall/headboard, at the other end for example, they always fall off.
Nah, I can't sleep like that either.
Attitude is everything. You can look at the evil of the world, or you can see that good comes out of everything. In the end, which will make your life more worthwhile?
