I have a sound machine for our guests to use while they’re here. I take one when I travel, too, so I don’t have to listen to city noises. It’s very compact with lots of choices.

I will check that out; I’ll bet it’s very soothing. I might actually like that for myself!
I don’t want guests getting TOO comfortable, you know? ;)
