Thank you for your feedback. Rayray said he absolutely loves your class because you always share things he's interested in. Although he is still young and might not fully understand everything, that's perfectly fine. As long as he remains curious, we'd be grateful if you could continue sharing scientific knowledge with him. Additionally, since you're the only teacher offering this science course to him, if I forget to update the teaching materials after this unit, please feel free to proceed without waiting for me. Thank you so much!
