I really wonder if they are just that clueless or something else.
In my line of work, you don't see nearly as many men as there are women. The few that I have personally worked with or encountered all do the same damn things. Like talk loud, and constantly. Do not put cell phones on vibrate/mute when working a large room with other people.
I'm in a room working, and there are several other people in here. I treat it like a library- quiet and respectful of others. THere are two guys working together in here. They keep talking and loudly. I have my noise cancelling earbuds in and I can still make out what they are saying. Plus one dude's cell phone keeps ringing.
And I really just want to turn around and give them a librarian hush.
