This might be a newbie question but maybe the group has an opinion on this. We are told a lot that we should show rather than tell -- I get told this by reviewers, probably because my non-fiction writing background leans very heavily towards telling rather than showing. What about phrases that express the internal emotional state of the POV character, though? Is it OK to say "X was shocked" if X is the POV character, rather than having to say "X gasped and stared", or similar?
