I'm not a beginning writer and/but there are things that, in a way, I've never gotten over. These turn up in disguise in my work and propel, sometimes, the whole enterprise. I was about ten and on vacation with my parents at Lake of the Ozarks. (Now Branson, MO.) I was skinny and self-conscious, like a lot of kids. Walking to the dock one day wearing a stupid swim suit with fish on it, some older girls laughed. Maybe not even at me, but that perceived humiliation is Ben's in STONER & SPAZ. Lucky me, huh?
Why be humiliated about humiliation? Why be embarrassed about those experiences. Revisit them. Have them over for drinks and chips. Tell them you've got some work for them to do, but first a nice dinner with lots of white wine!
