Eventually he wrote to the department of agriculture.

Dear sirs, he began. During the past few years I have had a prolific outbreak of dandelions all over my bluegrass lawn. I have tried everything. I have cut them, sprayed them and weeded them. I even tried letting my mother loose on them, she likes to make dandelion tea. All of this has been in vain. You are my last hope. Will you please help me?

In a couple of weeks he received a surprisingly brief reply. Dear sir, seeing as you have tried everything in an attempt to obliterate your dandelions, you have only one alternative left. We suggest that you learn to love them.
