I was walking my dog one night, a big 100+ pound greyhound. His size is intimidating. Like any sighthound, things in motion fascinate him. A cute teenage girl was riding her bike on the sidewalk toward us. The street is so unsafe that that's the only way to stay alive. She fixated on my dog in fear. He stared back with an intense gaze, He loves girls. Poor little dear didn't see the signpost in front of her, smacked it and went down gracefully. Now doggy was really happy. I had to manhandle him out of there.
