Why did the woman remember James so well?

M: Do you know James? He is in your class．
W: Certainly, in fact, he was the first person I got to know in my class．I still remember the look on his face when he showed up late on the first day of school．

M: I wonder if Sue will be here by 5 o’clock．
W: Her husband said she left home at 4:30．She should be here at 5:10, or 5:15 at the latest．
