It's too wet.

It's getting late and it's too dangerous to use a mower in the dark.I can't mow the lawn now.

The sun is shining and it would burn the freshly cut grass.

Grass has feelings, too.

I'm letting the lawn revert to its natural state.

If the grass grows high enough, I won't need curtains.

I'm planning on getting sheep, and they'll crop it.

A messy lawn keeps the tax assessment down.

I'm trying to get back to my roots. I reject the concept of a monoculture. Our caveman brothers never mowed their lawns.

I'm waiting for an enterprising kid to come along. Lawns should be cut by kids. Keeps them out of trouble, and teaches them the value of a nickel.
