Are the whippersnappers always on your lawn because they find it so comfy, or just to get your goat?

Ever since I tied my goat up in the driveway, them dang whippersnappers don't get on my lawn (but now how am I supposed to mow it?  Hire a whippersnapper?  They'd have to get on my lawn to mow it.  That's why I got a goat in the first place.)
