An act of kindness....
A travel agent looked up from his desk to see an older lady and an older gentleman peering in the shop window at the posters showing the glamorous destinations around the world. The agent had had a good week and the dejected couple looking in the window gave him a rare feeling of generosity.
He called them into his shop and said, "I know that on your pension you could never hope to have a holiday, so I am sending you off to a fabulous resort at my expense, and I won't take no for an answer."
He took them inside and asked his secretary to write two flight tickets and book a room in a five star hotel. They, as can be expected, gladly accepted, and were on their way.
About a month later the little lady came in to his shop.
"And how did you like your holiday?" he asked eagerly.
"The flight was exciting and the room was lovely," she said. "I've come to thank you. But, one thing puzzled me. Who was that old guy I had to share the room with?"

Ford Canada establishedIn 1904, Ford Motor Company of Canada was organized when Henry Ford signed an agreement with Gordon McGregor, a Canadian wagon builder. McGregor, age 31, had taken the initiative to vist Ford in Detroit earlier in the year because he wanted to begin making cars at his wagon works in Windsor, Ontario. Incorporation of Ford Motor Company of Canada was in the form of a Provinicial Charter issued on 17 Aug 1904. McGregor would finance his own operation, and 51% of the stock would be assigned to the Shareholders of Ford U.S.A. McGregor also obtained the rights to sell Ford products in the then existing British Empire outside of the British Isles. This foresight led to Ford of Canada to later having wholly-owned subsidiaries in Australia, New Zealand and South Africa.« |
