In or out
of 'em, it doesn't matter.
Nothing seems really to matter,
that's the charm of it.
Whether you get away,
or whether you don't;
whether you arrive at your destination
or whether you reach somewhere else,
or whether you never get anywhere at all,
you're always busy, and you never do anything in particular;
and when you've done it there's always something else to do,
and you can do it if you like, but you'd much better not."
