It's amazing how powerful words are - written or spoken. In books, blogs, magazines, etc, the right words put together, can create one amazingly striking message, or evoke an unbelievably powerful emotion. As a reader, I yearn for this. If what I am reading does not make me laugh uncontrollably, or cry out in anger or sadness, then I quickly lose interest, as do all readers. In my own writing I strive to reach deep into my soul and pull out the most extreme emotions, turning it into what I hope is a well thought out and impactful story. One that will have readers wanting more. The way I see it, if I don't express emotion myself as I'm writing then it's not worth it.
I still remember the day I read a certain part in the last Harry Potter book (SPOILER AHEAD). Though if you haven't read the books by now, come on! I have no words for you.
But the chapter where Fred dies is what got me. I ended the chapter, set the book on my bed, and balled my eyes out for a good 20 minutes. (If you don't remember, Fred was one half of the Weasley twins, always cracking jokes. I've attached an image below.)
