I must have learned this response somewhere. I hypothesize that I learned it from other passersby when I was inconsiderate or acted the fool during my youth.
I know I learned some lessons that way; )
To be completely honest though, I do very similar things, I will avoid getting out of someone's way to the extent they attempt not to get in my way. After watching enough videos on Russian drivers, I'm wondering if there isn't something going on with peripheral vision among Slavic people.
On a somewhat contradictory and related point: one of my colleagues told me he's asked a few of the co-workers in his department if they are self-observant/self-critical. They laughed at the idea that anyone would even question one's own actions.
It would explain the "my sh*t don't stink" attitude I've seen among a segment of the population where I live. There's a combination of things at play with different people but this is all a digression.
Suffice to say, the approach towards conducting oneself in public seems to be different here in many ways and that's just how it is.
