IELTS Speaking topic: A time when you feel surprised to meet someone

Describe a time when you feel surprised to meet someone.
You should say:
when this happened
who this person was
what did you do together on that day
and explain why you thought it was a surprise to meet this person.

Let me tell you about a time when I met with my friend in the airport in Beijing. That was in the end of last year, when the Spring Festival was coming, and I was going back to my hometown. I was reading a magazine while waiting for my flight, then I heard a voice calling my name. I looked around and found that my old friend was standing in front of me and smiling at me. It was so surprise because you know, it was nearly impossible to meet a person you know in such a big city and we even would take the same flight to the same destination. He was taking a business trip to my hometown.

It was so exciting to meet old friend and we hadn’t seen each other for two years, so we had lots of things to talk about. We shared a drink in the cafe and talked about the past things happened during the two years. The waiting hours passed very quickly and before we started to board, we left each other’s telephone and promised to keep in touch in the future regularly.
