I like to chat with strangers on trains then my conversational/oral mandarin is good enough to do that. NOWHERE do I claim to be able to read or write han zi well.

Now, no, no, what we are talking about is rudeness.

Noisy fat chinese fella shouting 4 floors up at 7:50 am this morning could simply have used his lump of plastic to give his mate a quick bell, instead of shrilly repeating his name at the top of his voice, screaming his lungs out for all to hear. So while I think mobiles are a nuisance at times, especially on trains, they are a convenience and blessing at others.

Plus all that radiation is really good for your brain, it does not cause brain cancer, and may keep you sharp in thinking and make you slim? Sarcasm filter optional:D

Must go my boy, studentesses to meet.
