to your opponent, again I think everyone is brough up differently and have their own opinions on this but I've got questions. Personally I see know reason to give your opponents props/praise no matter what, again this is my personal opinion. Why do I feel this way? Well b/c when Im out on the court, its all about me, not my opponent, even when im not on a tennis court or im playing a video/or board game, its all about me, and the only time the opponent is really in the matter is the fact that they are in my way of me accomplishing something. So for tennis, the opponent to me, more so is not just a player on the other side of the net, they are like an infection, a henderince in my side, a headache im trying to get rid of, so I personally don't feel like i need to give the any respect or praise, for im trying to get them out of my way, so i can go for my gaol or win the match
Why even bother complimenting an opponent when you win or loose against them?
Why raise a racquet when your ball hits the net and barely bounces over for the winner?
Why apologize for tossin the ball wrong and having to retoss it, (if anything you shouldn't be saying sorry, but should be telling yourself to get it together/right)
Why aplogize for hitting your opponent (personally if they got hit, they were wanting to be hit, i don't care how close we were to the net and the ball, you could've moved, and if you guess the wrong way? guess their just shit out of luck, and "better luck nextime")
All these, I think are just "Traditions" from tennis that have just been kept up. I Personally do no aplogizing on the tennis court, or when im playing a game. Maybe b/c i know im good, and the fact that im very competitive has much to do with it along with the fact that I was brought up to not be a pussy, and I am the best, i am the 1 that matters.
