My Vandal in Training Mother

Today my mom spray painted a couple of stands and a starfish. She painted them black. We had to move somethings along with our cats out of the garage before spraying. Then my mom made me read the directions even though she already claimed to know how to spraypaint. How do I point it? Where is the button? Do I remove this? Questions like that. Then it did not smell very pleasent and I am still smelling it right now in the house.
