Katara was a very skilled waterbender, probably THE best waterbender. So you decided to ask her for some tips since you were also a waterbender. She kindly agreed, and you both walked over towards the nearest body of water. As you both started to waterbend, she noticed something was off. She walked over to you and placed her hands on your shoulders, gently moving you around.

"Here. Your stance is a little stiff, and your arms are a bit close together." She said as she helped you fix your stance.
