Same thing goes on in Italian. As my Grandmother would say "it doesn't sound good in english.
I won't even go into Italian nick names.
Both cultures are very close..EX.
I have an Uncle Izzy and an Uncle Frank. I sware these guys are the same person. At any family function, I've never seen them both in the same room at the same time.
We're starting to thin out too. I married an Irish/German girl, Whom I love dearly. But the Family (the older ones) refer to her as "De Amedagan" (the american)
Happy Trails
