Guys at the shows and cruises are really rude

I was raised around restoring cars and going to car shows. Even as a child I knew not to touch, lean or sit on ANY part of a car that is not yours. Mind you this is at 5 years old. Guess at 5 I was more mature than most middle aged grown men. I love taking my car to shows and I could honestly care less what people have to say about my car. The only car shows that I choose to attend now are usually all mopar. It's nice to be around people that share your same passion and can relate to your vehicle.
Parents now a days don't know or are afraid to discipline their kids and explain to them why it's not right to touch or lean on other people's stuff! I saw a kid with a toy truck running it all down the side of a beautiful street rod while the ******* parent sat their and did nothing and watched! I went over to the parent and let him have it, and it wasn't even my car! I really don't understand society and how kids are being raised these days. The future is going to be interesting and no wonder why the world is going to ****.
