In that empty sketchbook (Nothing in particular)

While on a walk, I happened to look up at the sky and saw a single contrail in the clear blue sky without a single cloud. This is the song that came to mind during that walk.
It got me wondering: if you drew a big picture in the cloudless sky, would it look like a doodle on a globe when viewed from space? That'd be interesting. It would be interesting if someone who has the opportunity to go out into space could answer such a question.

This time, since I've just started streaming, I thought I'd add some singing to the stream.
