I came home yesterday and started singing a particularly famous christmas song that I will not name in fear of infecting you with the virus. But I hadn't heard the song anywhere, or at least I could not remember. Out loud, I began to sing it, right there in the kitchen, and when I realized it I felt fear. Now it's gone again, and I don't know when it'll come back.

Was the weather outside frightful?

That's what came to mind reading your comment.

Please don't do this

I was thinking of that one called “Merry Christmas” in Spanish

Don’t go outside

Or go very, very, very far outside. Like, into the woods. This may be necessary if you have inconsiderate neighbors playing Christmas music you can hear through the walls.
