Be a potato. A spud. An earth fruit. The brain often tells us to just sit down. Preferably on something soft and comfortable. Dry. Soft. Bug-free. Moldless. No thorns or spikes or razors sticking up.
The couch was invented for us to sit. Rarely do I need a sign to tell me to stop and offer me a place to sit. More likely, I need a sign to tell me to go.
