1. When the phone rang, I came in. (This means I might have heard it from outside (for example) and came in to answer the phone) or While the phone was ringing I came in. (This means it was a coincidence.) 2. I am sorry that I was late. However, this is not commonly used. I, personally, say: Sorry for being late.

Hello, 1 When the phone rang, I came in. 2. I'm sorry that I was late/ I'm sorry that I'm late. These are more common and informal sentences. Well done!

1 When the phone rang, I came in. 2 I am sorry that I was late. Hope that helps, Wade.
