An odd tribute

I was driving down the road the other day when I saw this:


This just seems like a rather odd tribute to your son...Why would you call your son your "problem child" and then plaster it on the back of your vehicle after he had passed away?

I just don't understand what goes through some people's minds.

(And yes, I obviously changed the poor guys name. I mean he's already having his named bashed all around town as his parents drive around. I wasn't going to do him the same injustice all over the internet).
