We must have been out of our minds

We said our goodbye long ago never thinking we'd miss each other so all the memories we must leave behind or we will just go out of our minds
I thought i loved another not you oh, how foolish i felt the same too
They both turned out to be the wrong kind ah we must have been out of our minds
Lets forgive and forget the life we've known and cast aside all the seeds we have sown surely they can forgive us in time oh we must have been out of our minds
Did it just turn out to be the wrong time or did we just go out of our minds
