How to send a circle of friends when standing guard at school?

The reference to this copy is as follows:

1, today's duty guard, although a little hard, but to see the students safe and happy, I think everything is worth it.

2. The time of standing guard is always particularly meaningful, which makes me understand the responsibility and the value of paying. I hope everyone can cherish this guardian.

3. Every day at school, I am here silently guarding. Although you can't speak, my actions can make you feel safe. I hope you can understand my existence.

Although standing guard is very tired, I feel very happy every time I see those energetic faces. Because I know I'm guarding your future.
