timing and placement

I keep a wooden serving tray next to my reading chair in the living room. It acts as an end table, so that I can have a place to keep my books, pens, and morning coffee. This morning I accidentally bumped into the tray and sent everything on it sprawling all over the livingroom. I'm grateful for two things -- First, that I had already removed the coffee and put it in the kitchen (no coffee stain on the carpet), and second that the water I did spill managed to soak everything that had been on the tray -- EXCEPT my cell phone, which missed the center of chaos and managed to stay dry.
