Do you believe in coincidences?
Just this morning Mrs. Grouch and I had breakfast with one of our daughters and son-in-law. I'm not sure how the topic came up but we discussed which of our kids gets the responsibility of telling me when it's time to give up the car keys. We decided on our youngest son. He'll let me go on the longest and he'll be the most insistant when the time comes.
Now that's plotting my decline!
FWIW, I'm not planning on giving up the keys anytime soon. I'm still driving a school bus every day. Starting in 2013, I'll have to pass a practical and driving test every year in order to maintain my CDL.
