Let's follow-on from the previous post in a roundabout way. Is the metaphorical glass half-full or half-empty? The boys from Liverpool shed some light on the question in a way perhaps only a Brit could - using rain as an analogy.
Incidentally, in my opinion the mark of an excellent band or artist can sometimes be gauged by the strength of their B-sides. In the case of The Beatles - and this song in particular - this excellence is self-evident.
