Hello how may I help you? My brother and want to learn to play catch. How does the game work? Catch is generally defined as a game where two or more people toss an object, usually a ball, between themselves. Are there any rules about where you can throw the ball? In general, there are no specific rules. Variations of the game are agreed upon by the players. Would you like to hear some common variations? Sure. I want to have a safe version that doesn't involve pain. Ok. The safest way to play catch is to stand about 15 feet apart and gently toss the ball toward the other person's hands. The underhand toss is typically slower. Okay we can do that. Should I wear safety equipment like a baseball catcher does when we play? Safety equipment is recommended, though not required. Okay. With my brother I will definitely wear some. Thanks for the help. Thank you and have fun!
