When people ask you a ton of art questions that you don't know the answer to.
When random people think they know everything there is to know about art when they don't even know what the heck anime is.
When lawyers ask for discounts on your art prints.
When someone asks what style your art is in when it's quite obviously anime/manga style.
When people ask you why you don't just buy the art supplies that you want that day.
When people who know NOTHING about art ask you why you put THAT EXACT THING THERE and you can't say something poetic to explain because they don't know ANYTHING about art and they focus too much on logic.
Comment below about any of these that have happened to you.
