You can learn a lot about your neighbors from their lawn.
Your lawn is the public face of your home, a chance to show off your interior decorating skills on the outside of your home. If nothing else, it shows everyone on your street that you can care for a complex, temperamental living organism.
The home of a responsible family... or a lazy gay couple.
Or, you can show them just how far you're will to let yourself go, clutter it with more plastic figurines than a spoiled rich kid's play room, and generally let your freak flag fly.
While the let yourself go option might sound easier, that's only because you're not using your imagination. Specifically, the crazy part of your imagination.
Because where else is the house plant going to sit?
