I think one of the best way to learn about someone is through what they love:
Milky oolong (top 10 scents in the world)
Nostalgic foods
Yapping about passions or random topics
and hate:
Hypocrites
The loss of the human touch
Experiences that rely on exclusivity
What else...I'm currently obsessed with writing as a practice and tractile experiences/products. Best thing I've seen recently was Pixar's Soul and my best recent bite was the classic egg tart from NaiSnow.
