Another incident to add to the "sightings". This happened to me outside Sim Lim Square, where a lady who spoke with a Malaysian Chinese accent started telling me a story of how her mother was ill and she had no money to buy porridge for her. Might be the same person that Drudkh met.
What I did was to act blur, she first asked if I understood Mandarin, then blah blah her story in Mandarin, then look at me as if I don't understand (act blur face), then switched between Mandarin and English. Just politely declined and walked away.
