There was once an Astronomer whose habit it was to go out at night and observe the stars. One night, as he was walking about outside the town gates, gazing up absorbed into the sky and not looking where he was going, he fell into a dry well. As he lay there groaning, some one passing by heard him, and, coming to the edge of the well, looked down and, on learning what had happened, said, "If you really mean to say that you were looking so hard at the sky that you didn't even see where your feet were carrying you along the ground, it appears to me that you deserve all you've got."
