Muley just appeared on behalf of the UCP

There are different degrees of Cerebral Palsey (per my understanding) and it would depend on what degree one is in as to whether or not they could perform puppetry--or at least what KIND of puppetry.
Puppetry is inclusive of many different styles. Of course, there's the most popular Muppet-type puppets (the kind I consider that Muley is) and there are marionettes and little hand puppets and so on; but it also comes in the form of story telling with even wooden spoons with faces, or dressed up like a male or female puppet.
I would say, yes, you can puppeteer, Aaron. I think that regardless what level of CP you have, you may find a way to tell stories using objects (puppets), and that would make you a puppeteer.
heck, I remember taping little drawn figures to pencils in grade school and telling a story to the class with those!
Puppetry comes in all forms and styles and techniques, and it's up to you to discover what you can do with it!
Wonder if Buck can add anything to this?
