Diary 25 Feb.

When I arrive at the bus stop, I recognize some students who are in my school. I usually say, "good morning" to them.

This morning, there was a person who greeted to me, and I also greeted back to her back.  
But, who is she? *** We had a simple conversation. She is a new student in my school who has been to here for one **** week. Perhaps she saw me every day, but I never noticed her. Her English is worse than mine, so I couldn't use the correct way to speak with her properly.

*** We usually try not to begin sentences with 'conjunctions' such as the word 'but'. Although when we speak in English, we often may say something like, "but, who is she?" when we write formal English we will try to write a sentence which is a more complete idea. For example, we might write, "I thought to myself, 'who is she?'" OR, "I didn't recognize her, and wondered who she was?"

**** In English writing/editing the numbers between zero and ten are usually written out in full form, not in numerals
