Taking care of your lawn is not only important, it’s the law. First you will need a lawnmower. Get one out of your garage. If you can’t find it, ask a neighbor where it is. Maybe they took it. Start up that lawn mower and push it over the grass. Make sure you are on your own lawn during this process. If you accidentally mowed your neighbors grass, go and tell them what you did, and maybe ask for a few bucks so it doesn’t get weird, you know?
