The aunt who asks about your art instead of your grades is seeing a part of you most people skip.

Being asked about the thing you actually care about is rarer than it should be. Most adults ask about school because it is the safe question. Somebody who asks about the drawing instead has noticed what you do when nobody is grading you, which is a better look at who you are. That kind of attention is a choice, and it takes a little effort to maintain.

Give that person something to work with. Show them the newest thing, even unfinished, and tell them what you are trying to get right. And ask them what they make or love, because people like that usually have something nobody asks about either.
