TA learning from each other

TOday i learned that I can learn from the other TA's while teaching the first years! I just listened to what the other TA's would say and what I would have said etc...
Each of us may know more about somethings than others and we can teach eachother. I learned today that when you scale one side of a tooth(lingual or Facial) if you've already done the other, quickly sweep the other side because the debri may get pushed into the other side. I never really thought about that. I may have known but not really. So anyways I learned that today!!
