Yes, acknowledgment of inappropriateness varies from person to person.
This fact is compounded by another fact that others will not bother to call for our attention when we behave inappropriately. When we are still kids, adults may chide and correct us if we behave inappropriately. But when we are grown-ups, others will hesitate to do so, for the fear of offending us.
The more we get offended when others kindly (taking the risk of offending us) point out our inappropriateness, the more hesitant others will become. The final loss ends up being our own.
Cases, which follow (or do not break) rules/laws, yet are inappropriate, abound. For example, a group of friends are having dinner at a host's house. Everybody has finished his meal, and has laid down his knife and fork. The host is waiting for the right time to serve desserts.
Well, what do you know, Tim Shih sees no sign posting on the wall the duration of eating a typical meal. So he continues indignantly to take his dear time to eat. Hey, let others wait for me. I am not breaking any rules.
I personally heard of complaints from a group of bridge players. All the players at 10 tables had finished a game, waiting to circulate the cards around, except at one table the game was still ongoing, and was delayed by one particular slow player. Every player was inconvenienced, but the biggest loss belonged to that particular player. He was disliked.
In our LG community here, the case may appear worse to me. We actually have two choices: (a) playing 10 games and hence spending more time in each game (b) playing 100 games and hence spending less time in each game.
If choice (a) and choice (b) make NO difference to others in terms of inconvenience, then, surely, it is none of others' business to expect us to pick either one. But the fact is that such choices do make difference.
True freedom of ours is to always keep others' freedom in mind. :)
