My dad. He was tired of us whistling all the time, and we were both out of tune back then, so it sounded perfectly awful when we whistled. The rule hasn't been taken down, so it still stands.
But by now it's pretty much dead. If someone's whistling and you're not wanting them to, you just say, "No whistling in the house." and it stops.
That reminds me of when I googled my name. A bunch of things listed the residents of the house I live in. It said that there were four people living here.
But it listed a fifth person.
There is apparently a forty year old Tatyana _______ (not posting my last name) that lives here.
I haven't seen her around.
