here was the conversation between me and "she" last night:
she: why it's so quiet?
me: really? it's quiet?
she: yes, usually it's time for trucks from other provinces to enter shanghai, and should be pretty noisy out there on the streets.
me: ah, i think it's as noisy as usual, but ... let me see. (i observed traffic on the streets for a while) ... you are quite right, there are much less trucks and cars.
she: isn't it a little weird? at first i think it's because i eat too much tonight and my hearing ability become dumb.
me: (LOL) i don't know why, maybe ... oh, i see why, it's Ahmadinejad!
she: ahmadi what? is that the name of a tornado?
me: it's Shanghai Coop Organization.
she: how lovely ahamadi-what is. how long he will stay in shanghai?
