Usually, while writing stories of my own, there are many times that I try to think of certain situations that would be seen as exciting/sad/angry/scary or lovable. The thing is, 9 times out of 10, the most memorable parts that people tell me about happen pretty much by accident. It's a few of those natural moments that I add simply to continue the flow of a story that end up being the most appreciated.
One that comes to mind is in "New Kid", where Randy and Ryan were going to spend a whole day together, and when Randy arrived, Ryan was eating a bowl of cereal for breakfast. That scene basically came out of nowhere, and I added to it more and more as I was writing, just to give it a playful, kinda comfortable, feel to it. And it ended up being a big favorite for a lot of fans of the series. That, to me, is always awesome because it's usually as much of a surprise to me as it is to others.
Another story that comes to mind was one that I saw on Nifty called "Always Joey", that really stuck with me because of its flirtatious vibe and because it was just an overall pleasure to read. If you ever get a chance, you'll notice certain moments of intense 'wanting' and 'longing' that I could really feel while I was reading. Also, there are extremely touching and heart warming moments in a story called "Just Hit Send" that truly tug at the heart strings. Another one (I hope I get the title right) was "Matthew Figures It Out", and "Carrots and Celery", and a few others. I won't get into listing a whole bunch, because that'll take all day. But there are plenty of stories where, when their titles are mentioned, my mind goes directly to a certain scene or a situation that really moved me in one way or the other, and I always try to structure my stories so that those moments can exist for other people too when they read my stuff.
Like I said before though, most of the time, they happen purely by accident. So I guess it's a matter of chance really, but as long as you write from the heart, the chances are better.
By the way, THANKS for the input so far! I'm really liking the answers I've read so far. I hope the questions in the future get just as much of a variety of answers as this one.
Any more?
