When we lived in northern Manitoba, mechanical problems had to be fixed by US. There were no technicians to call, no company to complain to. My husband just figured out how to get things going again. A dental clinic is a really complicated place. There are water lines, air hoses, suction devices, and all kinds of appliances. When we set up the practice, he put in all of this stuff himself. The clinic was in an apartment above Walter Perepeluk's grocery store. Rod and a friend worked for days to attach all the pipes, and this had to be done between the tiles on the ceiling of the store below. After a great deal of hard labour, it was announced that the pipes and the wiring were complete. We celebrated with a good dinner and a glass of wine. The next morning, however, when Rod went into the grocery store to check on his handiwork, Walter met him at the door with a strained look on his face. The entire ceiling, a network of plywood, panels, and tiles had fallen to the floor. The store was a mess of tiles, dust, and dirty produce. With more than a little fanfare, the new dentist had arrived!
