Why would you let your kid get so fat?

The people at the end of the row of townhouses perpendicular to our row are idiots. The husband is the size of Jabba the Hut and this wouldn't really bother me as much if he was just fat and not also annoying. Then they have a child who is probably about 7 or 8 and I'd say he weighs in around 140. He is morbidly obese just like daddy. So Jabba comes home for work every day and instead of parking and then walking across the street to the mailboxes, he drives to them. It is literally a total of maybe 12 steps from the end of his driveway to the mailboxes. So he drives up, blocking the entire entryway to the parking area for our row of townhouses. Then he turns around to pull into his own driveway. All while you are waiting to pull in. Then he looks at you like you are in his way.

So Jabba-in-training is now getting "exercise" every day. This consists of Jabba greasing his sides and smashing his fat ass into a lawn chair at the end of their driveway with a big gulp while Jabba Jr. whizzes back and forth on a mini motorcycle. He goes back and forth between their driveway and our driveway. There is no possible way to see this child on the motorbike when you are driving your car. So when you are backing out of the driveway or pulling in, he could be easily hit. So, you would think that Jabba would teach Jabba Jr. that cars can't see you so if you see a car, you need to stand up or get out of the way. But, this would make too much sense. So now, Jabba sits a giant orange sign at the end of their driveway that says "children at play." Since it is a blind turn to get into the road, there is absolutely no way to see the sign until you have already turned into the road and see lard ass perched there.

The thing that the worst is that if I were to hit this little brat, it would be my fault. My fault. Even though they are killing the kid with food and not forcing the porker to ride an actual real bike to burn calories. I would be sued for killing the kid. What is wrong with society?
