Subtle point: Teacher XX, people say that teachers are gardeners. How can I think you are the sun? It shines warmly on our little flower!
Life: Teacher XX, I feel like a long-lost brother (sister)!
Graduation season:
Subtle point: during the graduation season, I came to my former classroom, and I really want to write a sentence for you with the chalk you used in recent years. Thank you, my friend!
Life: After graduation, would you like to have a drink? I have long wanted to become sworn brothers with you!
Pure originality. I hope you will like it. (*^__^*)
