What do we say, "no offense" when we are about to offend someone?
It's because people are usually easily offended...
Or when you just want to offend a group of people that a person is part of, and not that person in particular...
Like you would say to me "No offense, but Brazilians are kinda crazy"... And I would not get offended...
But you couldn't say "No offense, but I think you're kinda fat"... It doesn't matter if that's true, you just don't say things like this!!!
Ok... got carried away...
Moving on...
