My hugging is an action from within. I open myself and show readers who I am. If they read my words and understand, they have received my hugs.
From the beginning stages of my professional writing, I've tried to be faithful and open about my pain, joy, triumph, and even stupidity.
That's my way to hug readers.
For me, hugging them is my way to symbolically wrap my arm around their shoulders and say, "Let's talk. I care about people like you. I want to pass on my mistakes and failures so you can avoid them."
I want to be open and loving to readers.
When I do that, I'm hugging them with my words.
