So to review: “if you’re playing tennis against someone who lives in the same house as you, treat their balls like your own… But if you’re playing against someone who lives elsewhere or you’re on a court next to other people not living with you, remember these tips”:
- Kick their balls
- To avoid confusion, mark your balls with an “X” or write your name on your balls.
-
IMPORTANTLY!: Don’t touch their balls with your hands.
