Interacting with different social cles?

You treat them as you would anyone else. Ignore the ist jokes, rude nicknames, lewd comments and lack of personal hygiene and just be pleasant and friendly. Prince William went to South America for six months to build a bridge in a poor remote village...he survived and so will you. He also cleaned toilets on his hands and knees, and since he is the future King of England, and leads a life none of us can even imagine, I think you can learn to tolerate the differences in your clmates.
