I understood the thread title about bullying, even though we say playground, and even though... a lot of bullying among school children now happens on the internet and can happen away from school, too.

Looking at the gripes on this thread, it seems a lot of people are easily annoyed. How can you find peace if such petty things bother you?

Language changes over time and it's perfectly natural. A hundred years from now, people will laugh at pronunciations of 2009. Now with the speed of travel and worldwide internet communication, languages will change even faster.
