How are you doing? In your last letter，you asked me about part-time work in your summer holiday. Now，I am writing to tell you my opinions.
To begin with, you can make some pocket money and develop a sense of independence. Besides, you can learn how to deal with various problems in the workplace. What's more, you can build up new friendships and improve better social skills. But as a middle school student，learning is most important for you. You should make full use of the holiday to study. My advice is this：make a detailed plan for your study and work and manage things properly.
Wish you a pleasant summer holiday.
