It all started with simple things such as who's hair looked better until their conversation led to who's better with children. The conversation got so heated up that students at the hallway could practically hear the two women argue non-stop until Tsunade walks out of the office demanding the boys to enter the room for a quick "Demonstration " to decide who's right!
A little while later, Naruto and Kakashi walks by the office looking for Kushina (Naruto just missed it!) XD
