This brain of mine

My brain, my brain
it's quite the thing
quite the awkward, funny thing.
Some days it's fine
sometimes it's (un) define (ed)
some nights it's swimming in wine.
Like rain, like thoughts
they go away
and come again another day,
if rain, if thoughts
could only stay
and never come another day.
I try, I'll try to refrain from rambling
but just so you know
just so it's known.....ahem....errrrr.....
my brain is a constant ramble
rumble
tumble
mumble.
