Tôi còn nhớ một kỉ niệm về thầy giáo dạy toán, kỉ niệ đó vẫn còn trong tôi mãi đến bây giờ. Khi đó là lúc tôi chuẩn bị thi Violympic toán cấp quốc gia, trước kì thi, tôi run và lo sợ lắm. Đang không biết phải làm gì thì thầy đã đến bên tôi động viên và khuyến khích. Cũng là nhờ tình cảm bao la của thầy dành cho tôi, mà lần đó, tôi đã an tâm đi thi và mang về một huy chương đồng. Chính tình cảm của thầy đã giúp tôi vượt qua nỗi sợ, nỗi bất an. Tôi phải cảm ơn thầy vì đã dạy dỗ tôi để nên người như ngày hôm nay. Tôi sẽ cố gắng đạt được nhiều thành tích tốt đẹp hơn để không phụ lòng thầy.
