[It's strange to see himself move like that. He knows for a fact he's never been that graceful in his life. He takes the arm (his arm) and wobbles his way over to the couch, sitting back down gratefully.]

Thanks.

...Dunno how you do it. Never realised it was so hard to move like this, but you make it look so easy.
