Last night, sitting in one of those 'Farmhouse-Restaurants', that I so like in Switzerland (a 'pub' in the middle of nowhere, where the locals congregate), someone sat himself next to me and greeted me with 'Hi Rob, haven't seen you for a long time, how are you ...'
Not recognising him, I looked at him more closely and wondered, once again, about how informal the Swiss can be. Then I recognised him as the 'Communications Engineer' that fitted my telephone, when I originally moved here.

He arrived at 8:30, spread out his tools and then said "It's almost 9:00; in Switzerland we have a break at 9:00" Then he disappeared for half an hour!

When he returned, I asked him his advice on a problem I had hit upon.
He gave me the best advice, a Handwerker could give ...

When I moved into this place, I decided, that it was not logical to have the bedroom opposite the kitchen/dining room and the (smaller) living room opposite the bathroom, but that was the way the flat had been laid out.

I decided to swap the two rooms around. This meant moving the TV/radio antennae and to do so, I had started to drill through the wall. After just a few seconds I hit metal and, not knowing what it might be, stopped immediately.

I asked my Engineer what, in his experience, the metal might be and he told me it was probably just a mortice and that he and his colleagues, in my situation, would just continue drilling - not a lot can really happen ...

Not being entirely satisfied with this answer, I made my original hole a little larger (he'd gone by then) and discovered that my metal was a water pipe for the central heating!
I suppose he was right - except for flooding the whole house and rendering the heating inoperative in January (with three feet of snow), not a lot would have happened ...
