Since you want to give the coach extra points, you can certainly praise you with banners, and the driving school can also be used as an advertising effect. So we must use positive words, not secular words.
Precautions:
1, if possible, hand in the pennant yourself. When you give it to the other person in person, this gift will have extra importance and significance, because at the same time, your voice, expression, even handshake or gentle hug will give the other person an emotional experience.
2. Banners express gratitude or respect to others. When sending a banner, you should have a correct attitude and behave gracefully. At the same time, pay attention to the content of the banner, use concise words, and don't have typos or grammatical errors.
