Is "negro" or even "black" offensive? I am reading To Kill A Mockingbird, and knowing there is a rude word we can never say. However, it thought the word "negro" was offensive as well but Atticus says it as a polite way. Also, is "black man" offensive? Thank you!

The School Starts Tomorrow, Heavy Snow We just had a short vacation, a "bonus weekend", from Thursday to Monday. We international students lived in Camp Kenwood, which is like a big dorm. Though it is unfair that we cannot go back home like the others, it is good that we can have free meals and be with friends, and probably those students are jealous of us! This is why people say "the grass is greener on the other side of the fence." However, I still have a lot of homework to do... I wish we could have a day off due to so heavy the snow. There is a storm warning today, and it's obvious that quite a few students cannot return on campus on time, but we still have class tomorrow! Last Tuesday, the snow was heavy, so we had a "Head's day". We feel cheated, because we could have a snow day, AND a Head's Day!

What should I say when someone says something good about me? Praises like "your bag looks good" or "your show was awesome"? Should I say "Thank you" or something else? Thank you!
