Toddler vs. Teenager

The other morning I walked into the front room where Dakota and Austin were having an argument.  As soon as Austin saw me come into the room, he ran over to me whining that Dakota was saying he was a toddler.  I responded "Austin, you are a toddler, what's the problem." Austin then argued, "I am not a toddler, I am a teenager!"  I tried  to explain to him that he was not and he continued to insist, "I AM A TEENAGER!"  Despite my explanation, he would not give in to the fact that he is a toddler.
