I've been pondering this all evening yesterday:
There are many situations in social life when it's nice to say something, as in ask about another person's life etc.
So not doing that can come across as, well, not particularly nice.
But are there situations when it's actually rude not to say anything?
As an example:
A co-worker of mine came in late yesterday because of a dentist appointment. She had mentioned a while ago that she's so sick of having to go there, she doesn't even want to talk about it anymore. So, when she came in yesterday and looked a bit down, I just gave her a sympathetic smile. However, another co-worker of ours asked how the appointment went and she actually told her a little about it.
So my question is:
Could my behavior in that situation be considered inconsiderate/rude/impolite, or is it just a case of "it would have been nice to ask"?
And, to your knowledge, are there situations when one must needs engage in conversation so as not to be rude (I don't mean when one's being addressed directly - that's kind of a given)?
