Replying to Tall Tees and newschoolers

so I was working yesterday and this kid comes in the shop wearing an oversized snow suit with a tall tee hanging out. this kid was no more than 13.. this older lady tells him that his shirt is hanging out and he says yeah it's supposed to with an attitude at this lady.. she asks what it's purpose is and he says i dunno it looks cool, so this lady says oh well i don't think so and walks away. haha this kid looked so upset it was hilarious, he then proceeded to go stare at the twins on the wall
