Ken: You can't be that busy! We hope you'll try your best to get here as fast as you can.

Mother: OK. It really isn't as bad as it seems. Can I speak to Cynthia and the kids for a minute, dear?

Ken: Sure, just a second…(Ken yells) Cynthia…Jon…Judy…
You know my new business, and I'm not as fast a worker as I used to be.
