I was standing in line at the supermarket, in front of a guy talking on his cell phone. His friend had apparently sprung some pearl of wisdom during their conversation, prompting him to reply, "Well, you learn something new every day!"
I thought, "No, you don't." It's a nice notion that, no matter how long you've lived or what you've done, you can always stand to learn something. But some days (today included) I didn't learn anything.
What do you learn? Your tolerance for alcohol? How late you can sleep and still arrive at work on time? How long you can listen to your cat whine for food (even though he just ate 10 minutes ago) until you give in and feed him again? Why you shouldn't put regular dish detergent in your dishwasher? How many items you can put on the "10 items or less" aisle before people complain? All valuable lessons, but you already knew that stuff. You just forgot.
Or that a year at Cornell University costs $52,000 and they don't give out any basketball scholarships, yet they can still beat a big-time basketball program like Temple in the NCAA tournament. There's a lesson for ya.
