Multi-culturalism is a word I do not like, and it rates just above "plague" in my own dictionary.
That is because I do not believe in the relativistic nature of that approach, which caused more harm than good: it left us in Europe with increasing levels of anomie, and that is bad according to positive psychology and to my own experience.
Not having a theoretical framework, though, that means i am more curious about cultural differences!
One thing I noticed just by reading the news is the different age labels.
It might happen that in England a 21-year-old man kills an 18 year old youth.
But in Italy a 33 - year - old youth runs over and kills two kids aged 22 and 23.
As a general rule, in England and in the USA:
"boy" : 10 - 15 year old dude
"youth": 15 -18 year old dude
"man": 18 year old or older
"boy": up to the age of 30
"youth": up to the age of 40
"man": 40 year old or older
Well, let's put it this way: I am very happy to become a "man" in 2009 in a Country full of boys, girls and youth! :-)
