If you’ve just nailed your opponent with a "Wilson sandwich," the unspoken rule of tennis is the "fake-apology wave." You raise your racket to look regretful, but deep down, you’re just glad the ball didn't land out. It’s the ultimate power move: maintaining the moral high ground while your opponent tries to figure out if that fuzzy yellow blur left a permanent mark. Just remember, a polite "sorry" keeps the match from turning into a dodgeball tournament—unless, of course, they were crowding the net, in which case they basically asked for it. Keep your poker face steady and check out more tennis etiquette tips to stay "classy" while you dominate.
