Yep, the West Indian Culture of Civility, among other things has been trashed. There really have been very few credible attempts to save the culture from my perspective. I have lived in St Lucia and USVI for the last 43 years so I have seen some change.

Isn't that how we identify groups (by their accents)...
We mimick each other to assure understanding...Tone and tune is very important when speaking languages...
I remember when I came to US I would see my cousins 'rolling' while watching TV...Even though I understood English I could not get the joke (could not get the accent or the punch)...
Until one day (don't know when) I discovered that I could detect the different American accents...

Village Manners VS Street Smart
Regarding our children (born abroad) with 'no village manners'...

Unfortunately, the first instructions they receive(for their own safety) is to 'beware of strangers' and 'mind your own business'...
We can't have it both ways 

I remember a roommate from Guyana , she helped an old lady cross the boulevard and when she check her coat pocket her wallet was gone...Then she remember how the 'old lady' was tugging at her coat and even ask to switch sides while she helped her across the street.

My brother came here very young with a college scholarship; nobody explained about racial issues, while they set him up in a white neighborhood...One day he was boarding the elevator and stop to help a white old lady with her shopping cart...Big mistake!
He said he will never forget the scandal; the woman screamed and collapsed; they called the police and the school had to reconfirm that he was a student living there...
He was lucky he did not encounter the "happy trigger"...

Luckily its not quite as bad as it used to be, although there are still plenty of people (usually older) with the old racial midset.

True.  I am always amazed at such people who have never left their town and never want to.  But perhaps that is the explorer in me talking.
