Acrylic paint thickens and hardens when stored incorrectly. My 16-year-old isn’t very good about making sure the tops of his paints are screwed on tightly or at all, and it’s been months since he’s touched them. The pandemic, it seems, has sucked every ounce of creative spark from my son’s soul. He’s sleeping more, but, honestly, so am I. Energy, motivation, and drive are hard to come by even for adults during these days. At a time when nothing seems to be normal, how do parents know when such changes in teenage behavior are normal?
