Just a yellow sky

A Spanish student who was learning English in Bournemouth once asked her tutor, "but what does it mean, that John Lennon song?"

"I didn't mean to hurt you,
I'm just a yellow sky" (sic).

Ah, John, the metaphysical Beatle. No, wait, wasn't that George?

Today I am mostly tired. The afternoon was sunny, and the children played outside, after a surprisingly cold morning. The internet was down, so I could not upload any observations.
