This has happened to me twice. Last year at a cruise I saw a teen looking very suspicious near my car (Frank/Bill you might remember this from Aurora). I kept watching him and then I notice that he is opening my door!

So I walk over to him and ask what he is doing. Just mumbles and walks away.
Then a few weeks ago a Mom, Dad and their young boy checking out my car at a cruise. And again the kid opens my door then slams it all while the parents watch it happen.

Again I say what the heck are you doing?! Neither the kid or parents say anything.
This happen to anyone else?
