Jesus, if you are 35 with a a master's degree and you think that your behavior is in any way appropriate, you have obviously failed to take advantage of your education. I teach master's students and if they expressed themselves in the manner you do, they'd do pretty poorly in my scientific writing course, where I really do criticize them for poor grammar. But hey, it's just a running board and it really doesn't matter, right?
If correcting grammar is the mark of this being a bad world, I cannot fathom where that places our current administration, what has happened in Darfur, the earthquake in China and the cyclone in Myanmar, but that's for another thread where we can all yell at each other once again, and call each other names. Because that is obviously the best way to make your case.
In the end, blown away, you never really did address the issue. You just tried to defend potential behavior which is pretty indefensible. So go yell at people every time they have an issue with you; good luck on your career advancement.
Bye bye now.
