Some time ago I had installed a couple of in-ceiling speakers into our living room. I did it one Saturday while my wife was out. That was a mistake.
When she got home she was disappointed that I had done this without consulting her. I had mistakenly thought that built-in gear would be inconspicuous and so desirable from her perspective. She, on the other hand, felt that cutting holes in the ceiling of our vintage 1920s craftsman style house was a bad idea. She’d rather leave it as original as possible.
