"For e'en his failings leaned to virtue's side."
I believe there are some husbands who grow tired of the married state after they have been in it a while. They came to find out that it isn't all "beer and skittles," as they first imagined it would be. Even "Puir Rabbie" had troubles of his own, as the following will show, for it is written about himself:
"Oh, that I had n'er been married!
I would never had nae care;
Now I've gotten wife and bairns,
And they cry crowdie ev'ry mair;
Three times crowdie in a day;
Gin ye crowdie ony mair,
Ye'll crowdie a' my meal away.
