I have found that to be true for everything in life.
I've driven plant all my life and you come across mouthy feckers all the time.ive done this and that types.
But they are useless on a machine.but the quiet 1s sat in the cabin are the 1s who can drive.they let the machine do the talking.
The same with dog men.
The dogs do the talking and you can clearly see the difference.no bragging is needed.
