Thank you. For something that was made in the 40's, I can't believe
that trained folks are so oblivious to the world around them.
There is "one step at a time", and there is "observe and immerse
oneself in the world they work in". Sometimes one gets in the way of
There are too many people that took a liking to my industry that
really should not be working in it. But then, there is no real work
ethic left about either. Why do I wonder? They pay any fool that has
