Road Crossing

Saw people crossing the road. Not that it happens rarely, but with me constantly putting my bike through its pace, though there no much left to explore of its pace now, rarely notice the way people crossing the road, ready to give up their lives right in under the front tyre of my bike. But yesterday i noticed and observed them much closely. Normally we just keep cursing the way people walk on roads or cross them, if you are a driver. So what i wondered yesterday is can we possibly understand things about someone's personality based on the way he crosses a street? Well, normally we do judge them, but thats superficial. Can their manner tell us in a matters of seconds about how that person is at work, or maybe how he lives life generally? I guess it should be pretty simple. Yesterday i saw a girl who started off from one end of the road, look and there were no vehicles coming from the right side so she started walking and even though she had not reached the divider, she did not look at that side again, and just concentrate on the other direction! i mean what if some vehicle had come from the right side before she reached the divider? Must be a very common occurance this, but could it tell us something about how this girl might be? I thought maybe taking up a tas but not completeling it before taking up another one? Apologies for being too judgemental and unfair even maybe about some random girl i don't even rememebr properly. But just a something that made me think there are so many things that tell us so many things about people, but we only choose to concentrate on a few things.
Atleast for me its about time i expand my horizon about what i gather from people's behaviour.
