The dog approached again, cautiously. I found the bologna sandwich, ripped off a chunk, wiped the cheap watery mustard off, then placed it on the sidewalk. The dog walked up to the bit of sandwich, put his nose to it, sniffed, then turned and walked off. This time he didn't look back. He accelerated down the street. No wonder I had been depressed all my life. I wasn't getting proper nourishment.
