Vyvian, I love how you're all "This is how it is. Deal with it." I hope writing through your PC with other personalities that might be mirrors of the walking world proves insightful for you.
Lauralyn, I wanted to respond on the idea of exaggeration, because I think that's a great way to give a character some starting aspects that are definitive to build off of. You have your static beginning, and can now say distinctly how you want to change your PC, and guide them through that process, and just create a fully round and dynamic character that way.
We're all low on post count, so there's definitely room to expand.
Lots of views and so few responses! Don't be chicken.
