Week 9 was about problem solving, and communication. What I thought was really interesting is how much of our communication is non verbal. A very small amount of communication is actually what we say. A larger portion is our tone. That makes a lot of sense. Someone could say something really nice, but have a tone of voice that tells you they are being sarcastic. The same can be true the other way. In regards to this, we learned how hurtful sarcasm can be in a marriage. The problem with this way of communicating  is that the other person may not always know when you are being sarcastic, so they will be very hurt. There is dangers in using sarcasm, in marriage or even with friends, so in all honesty, it is best to just stay away from it.
Back to communication, the biggest portion to communicating is actually with our body language. The way we stand, the way our face looks. It is the biggest factor in which we communicate. If we had a experiment where people tired to guess what the emotion someone was feeling by just looking at their face, I wonder if the results would be somewhat accurate.
