it's like real life - we don't get to see inside of people we have to empathise and, deduce! LOL :)

but in fiction this depends on whether the reader is sufficiently interested in the characters.

i don't like the idea of telling the reader everything: "I smiled broadly because i was so very happy, once i had been sad but now i was no longer upset and feeling guilty" etc.
except that actually, that's not necessarily a bad thing, it certainly might suit certain types or genres of story.

and i imagine an omniscient yet anonymous and constantly tight-lipped third person narrator could be annoying to some people!

well, these are just thoughts... but i might try re-balancing some of what i'm working on...

it is a bit of a tightrope to walk on as a writer, LOL!

and thank you as ever for the compliments :))
