Life in the US is not nearly the picnic most around the world think that it is, however, it is better in some respects than what other Countries have. With that being said the formalities of being "polite", there are those rules in other Countries that "WE" used to have i.e., traditional family values an respect for "elders", earn it b4 U get it, etc etc.
"You kids, with your phones and cameras....you have no idea what it takes to make you safe. Your very lucky to live in the US, if you do. Cherish it"
That highlighted quote from above, is why spent 30 years military to defend the rights an freedoms of others here and to ensure they have the choices to be foolish with their freedoms as they see fit. Its not that they will notice those rights they have now, until they are gone. However, when they do notice, those other "places" in the World, will be stunning, as they will have, what we foolishly gave away in the name of Progress an the "its all about me, in the here and now".
Keeping one safe- is a relative term- based upon what one does or doesn't care about, at the here an now--
