Is Common Courtesy Really That COMMON Anymore?

I fathom over this question every day as I ride the bus and train to and from my daily destinations. I observe the behavior of children (grade school and high school ages) & wonder (to be frank)...WTF? To be honest, some of these children act like animals!

I listen to the foul language coming out of their mouths (which we cursed when I was younger, but most of us didn't dare let an adult hear us) and there's just no respect, for those around them or themselves for that matter. Buses are crowded and they are pushing through passengers without an "excuse me", "sorry" or "pardon me". Really? Seriously?

My question is, what has happened within the last decade that people just don't care anymore? Why are parents neglecting to teach their children the rules of common courtesy and proper etiquette? Is it just me? Am I old-fashioned? I'm just shy of a generation older than most of these younger people I see...so, what in the heck has happened in such a short amount of time?

Don't get me wrong. I love listening to my iPod and listening to my jams, but I shouldn't be forced to in efforts to drown out the vulgarity I hear from these youngsters' mouths. It's a shame when the volume level from their "conversations" are competing with my electronic device, which I have to hold close to make sure one of them doesn't try to swipe in the first place.

I'm tired of getting shoved in the ovary or knocked in the back of the head with an oversized backpack because some rude child can't say "excuse me". I do love children (even though it may not sound like it), but I'm just sayin'...
