Write a paragraph on your favorite day of vacation using any six preposition

On 26th June, I celebrated my 15th birthday. At 8:00 p.m., everyone was gathered for my birthday party. After, I cut the cake, my sister took out a yellow box from under the table. I opened it and found a golden watch in it. It was really beautiful with all sort of design on it. Now I understood that my sister had gone to the Jewelry store actually, when she told me that she is going for a movie with her friend, and I was mad at her for leaving me at home.

its everything except for telling nonfiction and using first person
