I was playing a doubles match the other night in which one of our teammates told us that, on anything short, one of our opponents would always slap the ball too flat, so we should just duck and let it go out. Anyways, up a game point in a close second set, our opponents hit a deep one at my partner, who made a generic noise that sounded to me like "nah" after he hit it. Well, his shot landed short, and the infamous opponent slapped it my way around shoulder height. Having thought my partner had called the ball out, rather than hitting the easy volley, I did one of those moves where you try to catch the ball on your racket, just trying to avoid having to chase the ball down for the next point. But, my partner thought I was trying to leave it and just moved too slowly. Anyways, I started to change sides, thinking we had won the game, which initiated an interesting discussion between my partner and me. Apparently, he had tried to say "line" or something of the sort to warn me he hit a weak shot that was going to get abused. The ball was actually in, and I lost us the point. Luckily, we were both laid back about it and had a laugh.
