这幅图片是一幅动画插图，描绘了两个孩子坐在课堂上。左边的孩子是一个有着黑色卷发和红白格子口罩的男孩，右边是另一个戴着蓝色波点口罩的女孩，她有棕色头发并穿着白色衬衫。两人都坐着，似乎在认真听着看不见的人讲话。
背景包括一个绿板写着“返回学校”字样，暗示了关于重返校园的主题。板上还有其他涂鸦和画作，增添了课堂环境的氛围。
值得注意的特点包括两个孩子都戴着口罩，这表明该图片可能描绘了一个强调健康安全协议（如COVID-19大流行期间所见）的情景。

Both are seated as if paying attention to someone who cannot be seen.
The background includes a greenboard with "Back To School" written on it in chalk-like letters, hinting at the concept of returning to school. There is also other graffiti and artwork drawn around this board, adding an element of classroom ambiance.
Notable features include both children wearing masks, suggesting that this image may represent a scenario emphasizing health safety protocols (as seen during events like COVID-19 pandemic).
