I admit when someone recites a saying it can be annoying. If someone says "Show Don't Tell" without additional information, it is kind of thoughtless. However, if someone spells out the meaning or gives an example, then it is something I look forward to reading/hearing.
I wrote a sentence, 1: "Exploring around cautiously for a bit, she then smacked her fists down on the blankets of a bed, grumpy." The keywords here are cautiously and grumpy. It is telling not showing.
On edit, I rewrote, 2: "Exploring, she peeked around corners, lifted blankets, and sniffed the air while looking up at the ceiling. Smacking her fists down on the blankets of a bed, she glared at Soren, then looked away and crossed her arms."
I see the second sentences as much better. Some people react with, yeah but sometimes telling has its place. I do not deny that. This particular sentence though is one of the ones that should be rewritten to show not tell. If your response is, yeah but, then maybe you should consider if that's a knee jerk reaction to hearing it all the time. Do you know what "Show Don't Tell" means? Search it on Google or YouTube to find someone who explains it well to you if my Blog post does not help.
1: "She accidentally spilled her coffee." Sometimes you can spell the adverb (accidentally) out into more words.
2: "She leaned forward tilting her mug too much and spilling the coffee."
1: "He planted himself in the seat and adamantly refused to budge." Sometimes you can remove the adverb (adamantly) altogether.
2: "He planted himself in the seat and refused to budge." If you are refusing to budge, then you are adamant about it the whole time you are refusing. At the point you do budge, you are no longer adamant about it.
3: "He planted himself in the seat, and no matter how much his sister pulled on him he would not budge." You can decide which sentence is better. Hopefully, people will at least stop telling you to "Show Don't Tell."
