I'm guessing that the driveway chime is tripped by a beam like the cat catcher on electric garage door openers, or some type of motion detectors.
I once chased down an armed robber in broad daylight but I did not know that he was armed until he spun around and pointed a pistol at me. I jumped behind a tree and told the guy behind me chasing to let him go. The cops got him, I went to court and pointed at him from the stand and said, "that guy right there". Don't know what the final resolution was of the case, he was probably out way too soon.
When I was younger, up to about age 50, I could run like the wind and I would sock it out w some thug without thinking twice. I was fearless. I'm still not afraid of people w stupid tattoos and gym muscles but I'd probably be really disappointed in my old body if I had to throw down w someone younger and in shape.
