You & I have simply too much in common. My paternal grandfather was also a GP like yours - back in the horse & buggy days if you can believe. One time my grandmother accompanied him while 7 months pregnant with twins out to some farmer's home. Unfortunate while waiting in the buggy, the horses bolted down the lane & she lost the twins.
My father also was a GP - once treated a woman thro' her 9 month pregnancy, delivered the child, & looked after her for the 1st 3 months - all for nothing. (In those days Dad said they normally received $25) - oddly enough, a few months before Dad died he received a warm letter of thanks with a cheque for $2 -300 from this same woman who had never forgotten his kindness many years earlier. Tears flowed down his cheeks.
Such men in those days were very, very special - not rich, but wise & compassionate beyond words! During the Depression they were lucky to get $2/day. Got chickens, eggs etc instead.
