my boys are standing upside down in the clas?

My two sons are performing handstands in the classroom. They are situated at the front of the class near the blackboard, laughing with gleeful expressions. Their shirts have become lose around their waists, revealing their light blue undershirts. Their sneakers add a touch of color; one pair is bright red, and the other is neon green. Behind them, there's a chalk drawing of a sun on the blackboard, and wooden desks and chairs are neatly arranged.
