I am writing to apologize for using my phone during your lesson.As you know,I have a poor vocabulary so I can’t understand some of the class’s content .I was using my phone to look up some words so that I can understand your lecture.I really didn’t mean to break the rules.I’m terribly regretful for my behavior and I assure you that it will not happen again.I need my phone for study and keeping in touch with my friends and family.Would you please be kind to give me back the phone
