The thing here is, the kids get a lot of swear words from movies and they learn to use them as they do in the movies. We made our summer camp very cheap to allow students who don't usually do extra schooling to be able to come. The parents know in many cases these kids aren't very good students so they've asked us to include as many life skills with the teaching as we can. This is one of those life skills. In this case, yes, the child was quite innocent, in other cases, I've dealt with the isn't usually the case and this can lead to bullying and children leaving the school because they are being picked on and sworn at.
