Mr. Suspicious

When I opened the back door to take Lily for a walk a suspicious young man was walking through the parking lot. I lingered for a second and he flashed an artificial smile. I was walking behind him with my dog down the drive. He flashed a hand signal at Sleepy the drug dealer who was on the stairs across the street. When Mr. Suspicious turned left I saw his two buddies were waiting for him. I walked by with my dog and they were walking behind me. At one point my dog was held up sniffing something and the three guys walked past me. That was when I noticed Mr. Suspicious take a bowie knife out of his front right pocket and put it back in. I turned at the next block and walked back home.
