Tell: She stood still, too scared to move, and listened for someone approaching.
Show: She stood frozen in place, red skirt gripped in white knuckles, and struggled to hear anything above the pounding of her own heart.
Analysis: Instead of telling you she is scared, we show it--frozen in place... white knuckles... pounding heart... I am showing you what fear looks and feels like instead of telling you she is afraid.
Tell: Lini was so jealous, she couldn't fall asleep in spite of the fact that she was exhausted.
Show: Lini lay awake late into the night, fighting the little monster of hate plucking at her heart and keeping her aching body from sleep.
Analysis: I am showing you that Lini can't sleep and that she is exhausted... lay awake... keeping her aching body from sleep... because she's incredibly jealous of another woman... little monster of hate plucking at her heart.
Does this help? Is it any clearer or are you still trying to see the bottom of the show vs. tell pond through murky water? I found a few more awesome links on show vs. tell here, here and here.
And don't forget about the QueryTracker contest! The info should post today so hurry on over there after you've finished our session of Show and Tell. And have a wonderful weekend!
