Out of the mouth, the heart speaks

I was just having a conversation with a friend of mine, and she mentioned that she was living with 5 guys. I replied "sounds like the start of a porno flick". I realized after I said it that it was the wrong thing to say, and I was wondering why I said something like this? Somehow I realize I enjoy "pushing the envelope" of good taste and that it comes naturally. But more important is the verse Luke 6:45

^t?The good person out of the good treasure of his heart produces good, and the evil person out of his evil treasure produces ^u?evil, ^v?for out of the abundance of the heart his mouth speaks."

And I wonder what I have been putting in my heart, given what my mouth speaks. This isn't the first time that I've made a 'sexual' reference and had to retract it.

Last night I've realized that I haven't been keeping up my friendships. I think back to the last year, and the best and fun times that I have had were when the gang was together and the dumpling parties, the DDR, Lord of the Rings Trilogy and I haven't had anything like that since then. Makes me think that I made the wrong decision with Sue.
