True -- but only for the majority of the population which is wired to be able to understand others' behaviour. Anyone who lives on the autistic/Asperger's spectrum is likely to find this advice impossible to follow. The only way to analyze other people's behaviour is to ask questions, because behaviour itself doesn't carry any intrinsic meaning. One might as well analyze random numbers for all the good it'll do.

My own dose of Asperger's is extremely mild -- luckily for me -- but I still recoil from the idea of having to make accurate projections from others' behaviour. That's so difficult! It means studying people extremely closely (yet without creeping them out), figuring out which bits of their behaviour are significant and which ones are random, and then settling down to run through possibilities in my head until I figure out which are the likeliest scenarios ... there's so much room for error that I wouldn't want to stake anything truly important on the results. I'm told I'm usually pretty good at it, but truly, I much prefer Sasha's idea. Language is so much clearer.
