A e-mail I sent to my forign teacher today. Please have a look for mistakes The reason of this e-mail is the loss of my earphone which is a little bit expensive for me. Dear Shaun: I am one of your students in Eng 1A and I went to your lab and tutorial class in 14:30-16:30, 2017.04.01. Unfortunately, I lost my earphone that afternoon. I recalled that I picked it in my bag but had not take it out. I have no idea how it can be lost. May it was fell out in T401 or T516 but the teaching building was locked in this holiday, I cannot get in to find. Have you seen my earphone when you put the things in order after we have gone in T516? It was in a small black box. I am terrible sorry to bother you but please help me. (If there is any grammatical mistake please pay no attention to it....) Best wishes for you, sincerely yours, Derrick
