Cover up!

More evidence of culture shock:

I was walking in the middle of Central (downtown, business-y sort of place, lots of chain stores) with my mum, and she said what I was wearing was highly inappropriate.

I was wearing a T-shirt, USC gym shorts (mid thigh), and flipflops. Everyone around me was wearing business or business casual.

Clearly, I have yet to assimilate back into Hong Kong culture.
(However, if I'd worn a pair of trainers and claimed said outfit was workout gear, I might have gotten away with it.)
