Lawns are great for dogs, children to play, running around and growing weeds.
It's better than putting up another concrete jungle. We need green spaces.
Sure there is a fair amount of stupidly ridiculous front lawns of those in cul-de-sac or HOA type communities which could be made better. But surely they have some merit?
You complement my kid, and yeah, you'll see me smile. You show me my kids being good people, and you'll get a grin out of me. You show me my kids persevering when shit gets hard, and I'll giggle.
