The cats and I often sit in our nice warm lounge watching Robin working outside in the cold, cold garden.
Sometimes she will notice us and she will say something to us in a normal conversational tone of voice and at a normal volume. We have no trouble at all hearing and understanding her. The words penetrate the glass in the window as if it was not there. So we say something back, the cats and I.
Robin stares at us in a bewildered way.
"?" she says.
We try again.
"Can't hear you," she says, and goes back to her weeding.
It would seem that the glass in the window is preventing our voices from reaching Robin. Sound travels in from the outside but does not travel out from the inside. Obviously all the windows in my house have had the glass installed the wrong way round.
I now intend to go round to each window and reverse its polarity by turning it through 180 degrees in its frame. That way all the sounds inside my house will go outside, and all the outside sounds (including noisy cars and aeroplanes) will fail to enter the house, thus ensuring peace and tranquillity in all the rooms.
I will then sue the original glazier for failing to fit the glass the proper way round in the first place.
