The Perfect Lawn

Being an avid lawn nut, I refuse to permit weeds in my perfect lawn, and use herbicides each week. One night, a party guest was walking along the property line with my daughter. Seeing a sea of clover on my neighbour’s lawn, she noticed it came-up to my lawn and stopped. She asked my daughter why the clover didn’t cross-over onto my lawn.My daughter furrowed her brow, looked at the guest evenly and replied, “It wouldn’t dare !”
