Rude behavior has unfortunately become the norm. A sad state of affairs. Now rudeness, crudeness, swearing profusely and encroaching on others is considered okay.
Oh, don't get me started, but a friend of mine with an eleven year old was defending all the rap crap saying that it was her daughter's generation's way of expressing themselves and their freedom of speech. I kid you not. She said that nothing should be banned because it would infringe on their generation. HOGWASH! She was even including one song that her daughter was singing that said, Mother F---er! My God, I'm not a prude, by if I ever hear my granddaughter saying that, Nana will wash her mouth out with soap!!!
That trend in large part, is what endears me so much to the World WarII Generation and the simple values of decency and respect that I learned from being raised by "Greatest Generation" parents. Not to imply that they or any other entire generation is beyond reproach, but in general the raunchy language and behavior you see in our society today would never have been tolerated in public, or considered part of American "mainstream" culture. Kids today don't have a chance really, most are bombarded by the crude lyrics and behaviors from TV, movies, and "music" from the time they are 3.
That is why I find a great release in "spending time" in the WWII era, through books,DVDS and The History Channel, as well as listening to the Vets talk about their experiences. It allows me to at least temporarily escape back to a time when right and wrong were more easily defined.
