I met the late Lydia Sum Din-Ha (her name is also spelt as Lydia Shum) during a 2004 trip in Singapore, months before I went to Perth.
It was an afternoon, and we were eating at the Wo Men De restaurant, famous for its fish head curry. The restaurant was relatively empty that day, I think we were the only ones there.
Then all of a sudden, I heard the restaurant door opening behind me, I didn't turn back, until both my mom reacted.
"It's Lydia Sum." She said.
