Rethinking Rock Classics

I always assumed that the Beatles song "Hello, Goodbye" was about two lovers breaking up because they couldn't see eye to eye about things. After all, Paul wrote it after he had met Linda, but while he was still involved with Jane Asher:

You say yes, I say no
You say stop and I say go go go
You say goodbye and I say hello
I don't know why you say goodbye, I say hello

I say high, you say low
You say why and I say I don't know, oh no
You say goodbye and I say hello
Hello hello
I don't know why you say goodbye, I say hello

But now that I have a two-and-a-half-year-old, I know what it's really about: trying to get your kid to do something. Anything.

(Which is not to be confused with the Todd Rundgren album "Something/Anything?," which includes every kid's least-favorite song, "The Night The Carousel Burnt Down.")

It's not the only song that means something different than it used to; for example, I know now that "Another Brick In The Wall" isn't allegorical, but pretty much literal ("if you don't eat your meat, you can't have any pudding"). What other songs have changed meaning for you now that you've had kids?
