Jeff I feel for you. I don't care much for painting myself, but its not the painting I did lately that makes me relate to your story. Rather its the cedar shingling I did that makes me feel for your pain.
For me that job was just never ending. 28 square of shingles to put up and over a big area. It seemed like things were never ideal. You started out putting on the shingles stooped over, hit a fairly comfortable level only to go past that to working overhead. The gable ends were even worse and the days dragged on, the hours dragged by and it seems I was cutting and fitting shingles more than I ever thought possible.
But just as you are about to find out, its also very rewarding. The look of your place is well worth it and spending the time with the Mrs has its own reward. Too many married people spend so little time together (I am firmly in this camp) so even being together painting the house is time well spent.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
