Physical interactions with strangers. The pseudo-Brownian motion of people moving about in groups.

Those of us who are people-watchers, will, of course, be familiar with the many and various different ways that people move around. Those with a bit of acting knowledge may well have spotted many, if not all, of the Laban Efforts among the milling populace - few of us can have shopped in a modern supermarket, for instance, without having encountered a "float" (light, sustained, indirect) or a "wring" (heavy, sustained, indirect), blocking an aisle or two with their trolley, while they ponder the wonders arrayed before them on the shelves.

However, it's when people approach each other closely enough to interact, that things become a little odd. 
For instance, let us suppose that:

Person A bumps into person B (either a direct barge, as with, say a "punch" or "press" in pursuit of their chosen path, or through un-coordinated blundering, as with a "float" or "wring").

There seem, these days, to be two possible reactions:

1) Person A doesn't react at all, but continues, quite unaware of any social infringement.  Most of us, I think, would describe this as simply, "rudeness".

2) Person A emits an almost automatic "sorry", usually in apparent surprise that there should be any other people in the space at all, let alone nearby.

What concerns me, is that, for a whole generation now, reaction (2) is starting to be seen as "politeness".  Whereas once, that term might have been applied to such acts as, "letting other people pass" (and thanking those that do so), or indeed, "avoiding bumping into people in the first place."
An apology is, I daresay, better than nothing, but we do seem to be becoming a society of apologisers. I remember hearing Peter Ustinov speak about visiting an airport, and how he found himself walking across a vast, empty concourse, which contained only one other soul, who, amid the acres of emptiness, proceeded to bump straight into him, with a surprised, "oh I'm sorry."

Once, people were brought up to look where they were going. Once, people were encouraged to consider their words and deeds before taking any action.

Now, it seems, our peripheral vision, both actual and metaphorical, has become so limited, so self-focussed, that consideration for others has become encapsulated in a single word, no longer meant, no longer capable of possessing any meaning.

I've meandered around the point here rather, I'm afraid, being the "float" that I all too often am. If this has caused annoyance, then er... sorry.
