Could anyone help check mistakes please?
Thanks a lot!
When I just graduated from college, my older sister bought me a new phone, which is my first smartphone, and it cost her one month of salary.
I used the phone for the first few days and one night when I was on the way to my dorm, I put my phone into my pocket, and a guy walked quickly past me. After 1 minute, I reached out into my pocket and wanted to send a message, but my phone was lost. I realized the guy just past me had pickpocketed it. I ran up quickly, but could not find the pickpocket.
I was so sad since it was a new phone and it cost a lot. I cried that night and dreamt of finding it.
