It might be

Let's not make it into a big thing
Let's not get lost in this
I know it is,
I know we could
I guess we surely would
Let's pretend it's not
It doesn't mean a thing
Let's not blow it out of all sense
As though it meant so much
It's always thought about for weeks
Not every time your lips meet mine,
I think of her

But when her hands reach out, I think of you
