It's important to get your timing right. . .

That's good! Whenever the cleaning crew mops and waxes our halls at work, I guess the hall to my office is always last to get done and almost invariably I'll have to walk on it while the poor woman's still mopping it. I always apologize and say, "Ya' know, my Mama woulda' spanked my butt for doing this!" She always replies, "Oh, that's OK, child. You got your job, I got mine."
