Rule number two, don’t walk in someone’s line on the putting green. This is a big one. Your line is the imaginary path between the golf ball and the hole. Walking across it can leave subtle footprints or marks on the green, which might change the way the ball rolls. Even if you think you’re light on your feet, it’s just bad etiquette. Always walk around behind the player’s ball or a little wide of their line. It shows awareness and it shows respect for the effort they’re putting into making their putt. Jumping over a line is not proper etiquette, even if you don’t physically step on
