A mucker is someone who slows down and prevents good communication from happening. What the Muck? outlines four basic ways to clean up communication.

• Listening vs. Waiting to Talk
  A lot of people when they are listening are not actually listening and are instead wondering when it is their turn. One of the number one things is to make sure that when someone is talking to you, you are listening and really taking in the information so when you start to talk it is suitable for the conversation.

• Scene Stealer
  This is someone who actually might be very interested in what the other person is saying but they never let the other person finish. It is not that they are not positive or supportive, but it is that they get right into it. That is the ability to not allow someone else to say what they want to say and they just take it away from you.

• Top This
  Whatever someone is sharing, this person feels the need to go right up there and top the other person. This comes from the person's natural need to feel significant. It is a habit. If you make people feel little, chances are they will stop talking to you because you are always one step ahead or better than they are.

• Blind Question
  This type of question is where the person asking it has all the information so he can make the decision. They are dangerous and can lead to the other person losing trust in you so that every time you ask a question, they may or not be honest with you simply because the last time they were set up.
