It's a small world after all

Just came back from H.K. last night.
It is now the summer holidays in H.K. as well as in China.
The streets of Hong Kong were exceptionally overcrowded with locals as well as foreigners. Almost every step we made we must be careful not to step on somebody's shoes in front.
While we were walking the busy streets of H.K., a thought came across my mind.
Looking at the great amount of people all around,I was thinking it must be truly unlikely to bump into somebody we know .
Yes, we did not meet anybody familiar until we went to the Sea World.
The Sea World was another place packed with people from all over the world.
We missed two live dolphin shows due to the intensive crowding,and when it was time for the last show at 5pm, we started our walk to the vast open-aired theatre slightly before 4pm.
I happened to lead the line of procession of 5, and we finally found the best row of seats and sat down.........
I turned my head around to look at the guy next to me, and oh my, to my astonishment and disbelief, next to me sat Vicki , from POT Penang!
