以“my holiday”写一篇小短文介绍假期生活。用一般过去式来表达

The summer vacation is coming. We will have a two-month holiday. I am going to relax myself. I will visit my granparents and spend two weeks with them. I am going to help my grandparents with the housework. Of course, I am going hiking with my grandparents. Perhaps, I am going to take a short trip. My parents and I decide to go to the beach because we like swimming in the sea. Besides, I am going to visit my old friends. I think we will have a happy time together. I will be a middle school student in a new term, so I am going to make some preparations. I am sure, I will have a busy holiday.
