a teacher

Yesterday I saw someone I was very familar with in my secondary school.

I recognised her immediately.
But I was not sure whether she was really there.

Then I wondered whether I should say hi to her.

It took me more than 15 minutes to make the decision.

My colleagues and an old friend also thought I should.

So I went to her.

When I walked, she hid her smile.
I was wondering whether I should leave.
But I did not do so.

I told her a few times that I was a secondary school student of her.

She was the same.

She could not remember me. That's normal as she told our class years ago.

But she remember my school friend. Then she could locate which year I was in.

Surprisingly, she was very different from the teacher that I used to know.

She was quite happy and she gave me a hug.

"A historical moment", indeed.
