Several years ago, Andy was sentenced to prison. During his stay, he got along well with the guards and all his fellow inmates. The warden knew that, deep down, Andy was a good person. So, the warden made arrangements for the inmate to learn a trade while doing his time.

Some three years later, Andy was recognized as one of the best carpenters in the local area. Often, he would be given a weekend pass to do odd jobs for citizens of the community. And he always reported back to prison by early Sunday evening. Andy was a model inmate.

One day, the warden considered remodelling his kitchen, though he lacked the skills to build a set of kitchen cupboards and a large counter top. So he called Andy into his office and asked him to do the job for him.

To the warden's surprise, Andy simply refused to help.

"But you're an expert, Andy, and I really need your help," said the warden.

"Gosh, warden, I'd really like to help you, but counter fitting is what got me into prison in the first place."
