Short-Term Memory

I've always been a long-term person,
holding on, fighting to the bitter end-
never giving up on what I was in
no matter how far back I had to bend

but as I've grown older, I've learned
there are certain things you just can't change
and trying to do so is only wasting time
you can't keep everything in controlled range

so if you're not happy, go on and leave
I'm not going to fight or dwell in sorrow
there are plenty of other fish in the sea
I'll just dust off my fishin' poles tomorrow

It's not that I don't love you, I do,
if you want to leave, I can't make you stay-
short-term memory is much more my style
and it's why I love you for only today.
