Just wave back and keep running
From Create Your Own Story
You really don't have the time for him right now. Besides, who knows what sort of drama could pop up if you two started talking again. You just wave and keep on running. As you continue on your run, you notice what looks like some bum passed out on a bench, beer bottles all around. Another reminder as to why you prefer running in the morning instead of later in the day. You arrive back right in time to finish up your morning routine and be ready for school.
