Okay, so, I just watched as a young mother strolled along my street with her <2 year old kid. They stopped, then kid walked all the way down my driveway, into my backyard, and up to our swing set. The mom slowly followed, then sat the kid at the top of our slide so he/she could slide down. Then they left. Part of me thinks "get off my lawn", but a bigger part thinks it's cool that another kid got a smile from our slide!
