My Classroom Became My Art Studio

I know I should keep personal stuff out of the classroom, but when I’m not teaching, my classroom doubles as my art studio. It’s where I paint and sculpt whenever inspiration strikes. The kids catch me with oil paints drying on palettes and clay lumps half-finished into whatever shape my imagination conjures up that day. Who cares if it makes me look a bit messy? Do you think the principal would approve if she knew?
