I'm very good at crosswalks. When I walk up to a crosswalk, no tentativeness by me. Walk right through it because those are the rules. No game of "are you gonna go or should I go" with oncoming cars because that's my crosswalk and if the car has a problem with it, that's too damn bad for him.
On the other hand, when I drive and I approach a cross walk and someone wants to play the "should I walk" game with me at a crosswalk, I yell and make motions with my hands for them to cross. "IT'S A CROSSWALK. HURRY UP AND WALK!"
smdh. Millenials today don't know how to go up and grab the brass rings at crosswalks.
