Grouchy is in the eye of the beholder.
About thirty years back, a young couple moved onto a farm down the road, and he was trying to farm using both horses and a tractor, using each where most apropriate. He asked an old Dutch farmer from nearby to come over and give him some advice. When the old fellow walked into the barn to check out his team of Clydes, he took one look at the harness hanging on the wall and remarked, "If I'd hung harness like that, my old man would have beat the (tar) out of me!"
Young fellow, "You were really lucky to have a father like that."
Dutchman, "Didn't you hear me? I said he'd have beat me!"
Young fellow, "Yes, you were lucky to have someone to teach you how things should be done. I'm having to learn it the hard way."
So began a friendship that lasted til the old man died aboout 4 years later.
Sorry. I digress.
