Dear Jenny,
I have got you letter and have leart that you are going to take some part-time job during your summer vacation.You ask me for advice because you don't know which one to choose,as a tour guider or a private teacher.And I'm glad to share my opinion with you.
In my view,a tour guider needs to be outgoing,be fond of traveling,and be good at contacting different people.But a private teacher needs one to be very patient and stay at home for a long time.So according to your characters and capability,I think it is better for you to be a tour guider as you are very enthusiastic and active.You will enjoy the job and make many friends.
Best wishes.
Yours,
WangPeng
