Prov. You cannot control everything that happens to you.; You should accept the bad things that happen. Bill: I bought a hundred lottery tickets this week, but I still didn't win! Alan: That's the way the ball bounces. I was planning to have fun on my vacation, but I've been sick the whole time. I guess that's just the way the cookie crumbles. That's tough, but that's the way the mop flops.
