My dad is Puerto Rican and my mom is Italian and Irish.
Puerto Ricans: Known for their friendliness, open nature, very, very hospitable, once you are friends with one you are treated like family, they will give you the shirt off their back, very beautiful features, a mixture of beautiful races (the best aspects of european, african, and native taino indian), excellent cooking, known for some pretty famous singers (Ricky Martin, Olga Tanon to name a few). Probably the friendliest of all the hispanic ethnicites (Cubans and Dominicans as well).
Irish: Beautiful folklore, known for blonde and red hair, Celtic mythology, a rich history, they are also known for being quite friendly and family oriented. Also very traditional and spiritual. For anyone into Paganism they have one of the richest history and spiritual traditions.
Italian: (The ones from Italy, not the wannabes here) In Southern Italy many of them have darker skin and features (from Beber/Moor blood) and are very beautiful in appearance. Some of the men and women are absolutely gorgeous (the darker featured ones) and are known for fine arts, awesome food, and a beautiful country.
I'll even tell you the positive traits of some other ethnicities:
Filipinos: I know you guys are very hospitable as well, very clean, polite, considerate, and open to other people. I notice you guys are very inquisitive and like to get to know people (I work with a lot of Filipinos, many of them are very nice to just about everyone). Also known for good cooks :)
Dominicans: Also very beautiful and a bit friendlier than Puerto Ricans (in some cases). Awesome, awesome food and have the beautiful features and traits of the Taino/Africans
Mexicans: Very hard workers, strong family ties, some of them are the nicest, most polite people you'll ever meet, willing to take jobs that others scoff and look down upon and never complain about it. Beautiful country and excellent with their hands. Also beautiful people.
France: Beautiful language, once you make good friends with a French person they are friends for life, interesting culture, known for their romantic nature and beautiful women.
Cubans: Very traditional and family oriented, assimilates to American culture quite well, hard-working, white Cubans acknowledge they are white (and same with black Cubans) unlike other latino ethnicities who think they are a seperate race from others. Usually pretty nice people and some of them are quite good looking. Gloria Estefan is Cuban :-)
