I'm glad you replied to my advert
The one where I asked for a wife
You know that I live in the country
And the farmer's way is a hard life.

I'm glad that you're young and you're pretty
As pretty as I've ever seen
I'm glad that you want lots of children
And pleased that you're only sixteen

It's nice that you're fit and you're healthy
And that you're sturdy and strong
I'm grateful that you're not demanding
And you'll make love all the night long

Good news you fell out with your parents
And they live in a far distant land
I will cherish a life without in-laws
I am minded to ask for your hand

I read you're obedient and quiet
reluctant to nag or to moan
Your demure and modest demeanour
would melt this heart made of stone

Your reply is just missing one detail
It was in the small print of my ad
You didn't send me a photo
Of the tractor you said that you had
