Telling the emotion is telling. She loved him needs to be shown. How is love shown? I feel that no character, or author should "say" what the feeling is they are trying to convey.
Change the negatives into positives. When I tried to follow the rule 'Don't tell', I ended up writing unbelievable actions for the characters.
If you think about it, when you tell you're sacrificing a chance to show something about your character and indeed your voice as a writer. Maybe your voice is one which tells but chances are that it isn't.
'He thought her a fool'
Quite a formal stuffy way of saying it; let's say this is Character A's thoughts:
'He sneered at her inability to open the tin; the way she stabbed at it with a knife in that vulgar fashion.'
This is how Character B might think:
'Though it was pretty funny to watch Mary stabbing at the tin with a knife like some crazed murderess, B held back his laughter. She was silly, undeniably, but with that same conviction B knew she was his.'
If you're writing in omni, avoid judgement. 'Mary was ugly' is a judgement. If elaborated upon, it's forgiveable in 1st person as it allows you as a reader to get the sense of this character. Is he making a witty observation or is he cruel?
The other drawback with telling is that it can seem unconvincing to the reader. It looks like you're unable to show the emotion so we're just going to accept that he feels guilty and move on. If your character is fleshed out enough, sometimes their motivations aren't always clear, not even to you. Most people don't just feel 'guilty'- they have contradicting thoughts and emotions. One person might interpret it as guilty; someone else might interpret it as frustration at the person's failure.
