Two friends gather on a porch after a long day’s work. The one friend’s old dog comes to join them. The hound circles the area a few times and lays down right on the one popped-up nail on the decking. The friends shake their heads because the dog does this same thing every night.
“Why do you think he does that? There’s a whole porch and he chooses the spot with the popped up nail. Think he’s trying to tell me something?” the owner asked his friend.
The friend shook his head.
