About 13 years ago I was on a busy road and got in a wrong turn lane that would have put me on an interstate. I looked at the traffic and it was clear so I signaled and pulled back out to the next block. A city cop pulled me over and asked what I was doing and I told him.
Technically I had not broken any laws but it was risky move had traffic been coming. Had traffic been coming I wouldn't have tried it I told him. He said well you know what you did was dangerous so I'll tell you what I'm gonna do. All of the sudden in a Gomer Pyle voice he said fer shame fer shame fer shame laughing and said now get out of here. A cop who got his point across and we both had a good laugh.
He sounds like most of the officers I know. Easy going but knows when to be tough.
