If you give a girl a can of spray paint she'll probably love it. When she tries it out she'll realize that she needs way more than one color, so she'll ask you for more spray paint.
Then she'll get out all of the spray paint you have to find the best colors.
Once she has spray paint in every hue she'll want to make some art. Then you'll have to show her how to make a stencil.
Of course, once she has a stencil she will ask you for a wall.
Once she paints on the wall, others will be inspired and you won't be able to keep your kids in the classroom.
Instead, they'll be outside making murals. In fact, your whole trailer will be covered with works in progress.
Your kids will start seeing every empty wall as a blank state, full of potential for creating.
All because you gave a girl a can of spray paint.
