Twins. Part of the plot in my NaNoWriMo project required a case of mistaken identity, so instead of having one protagonist, I’m writing one and a half. I call the twins “one and a half” protagonists because I’m writing in the first person – so I’m getting all of what one of them thinks and only half of what the other does. They’re both good guys, Marcel and Max are. Decent men from a good family – very much the same in many ways.

As usual, something happened in real life which made me contemplate the differences between siblings. In this case it was a  conversation with the lady who manages the dry cleaner on my paper route.  She has two granddaughters who she loves to talk about. She was telling me how unalike they are, even though they’re very close in age. This is a subject (among many) that has always fascinated me, being an only child. My own children didn’t grow up as siblings usually do, since they all have such physical differences,  so it’s something I must study from a distance.

The difficulty I’m experiencing in my novel is that the twins, Marcel and Max, sound the same when they speak. It makes sense to me that they should, but they end up coming out like these guys:

Not all that polite mind you, but they speak exactly alike.

Once NaNo is done and I can put some thought into it, I’ll work on finding something unique about the two, which will come out in their speech. But in the meantime, I’m wondering what about their natures, and not their nurture, can help my readers to tell them apart.

Have you ever written siblings and come across this problem? Let’s learn from each other!
