The group I was in was full of high-school-aged boys. From first impressions, they seemed like fine guys; however, as camp progressed, they continually disgusted me with their crude humor, language, and constant use of double entendres.
In fact, hardly anything I said went without some sort of laugh over some double meaning I had tripped over; and these kids didn't seem to know anything other than four letter words to show their amusement. I won't put a list down here, but let it be sufficient that they would have made a sailor blush and then look for a priest to make confessions!
So, here's what I would like any teenage boys who read this to do: Carefully analyze what you do on a daily basis. Do you watch porn? STOP. Do you listen to music with bad language and barely concealed sex themes? STOP. If you find yourself using and thinking bad language (I won't define bad, you will know what it is) then STOP and consider using something different. It might seem lame at first, but really not saying anything in the place of an exclamation will really make a difference.
So there's my latest rant. Hope you enjoyed it!
