To me, as I look back at it, it seems that they must have succeeded wonderfully.

They were very happy, I believe--Father and Mother.
Oh, it was not always easy--even I could see that.

It took a lot of adjusting--a lot of rubbing off of square corners to keep the daily life running smoothly.

But when two persons are determined that it shall run smoothly--when each is steadfastly looking to the _other's_ happiness, not at his own--why, things just can't help smoothing out then.

But it takes them both.
