Was in my car, in the neighborhood, almost to my house. Two teens were throwing a football back and forth on the street. When they saw me approach they moved off the street, and as I drove by each one they raised their arms with their hands about 3 feet apart and slightly above their heads, the elbows bent. As if holding a large beach ball over their heads. I gave each a gentle wave and a friendly nod.
Never saw that gesture before. Must be generational.
Anybody have any idea?
