Including variety/unexpected moments with the stammer is something I didn't think of! I'll definitely try to sprinkle some of those moments, I think that would totally add to the realism. Thanks for the advice! And thank you for offering to read it, if this post is generally well accepted, I might make an update to announce the book itself when/if it gets published, so long as I can do so while not violating the no self promo rule :)
