chill out

Today I learned a new phrase "chill out" that means relax and enjoy and whatever makes people feel comfortable. My father told me that's a kind of slang and most black people like to use it. I didn't hang out these days because I have a lot tasks to do. I just talked to my friends through Internet and phone. When I was callingto my grandmother, they were celebrating chinese new year. Sounds great. Later I talked to my classmate, he tought a phrase" hang out" I didn't know that before. He said it's a very important phrase, I must know it. ..grin..I think my english will be better and better.
