Thanks, But No Thanks!

A Husband drew up his chair beside his wife while she was doing some work on her sewing machine.  "Don't you think you're running too fast?" he asked.  "Look out!  You'll sew the wrong section.  Slow down, watch your fingers! Steady!"

 

"What on earth is the matter with you?" his wife asked with alarm.  "I've been using this machine for years".

 

"Well, dear.  I thought you might like me to help you, since you are always helping me when I am driving the car!"
