It's bad when kids do something like that, but it's even worse when adults act so poorly.
I was in Germany last week, and visited the Dachau concentration camp near Munich. Over 200,000 people died there. It was the most emotional experience I've ever had. It was so sad and horrific that crying wasn't even an option. No one spoke for over four hours.
That was until I overheard some American tourists saying HORRIBLY nasty things about the victims and Hitler's regime. Needless to say I went carnival ape crazy, and after that, I didn't hear them say anything else.
It's a shame. A horrible shame.
