Dear Santa, (or Tooth Fairy, Easter Bunny, Great Pumpkin, etc): My name is Jen and I have been very good this year. I would like a pair of bionic legs. Or, a magic pill that would make mine work better (maybe 4Ap is it?). While you're at it, please bring some myelin sheath, too. I sure could use it - in fact, please bring enough so I can share with all of my friends on PLM. I promise to continue to be positive and remember that I can still have fun - even with this pain in the butt walker. Thanks much, Jen p.s. some chocolate would be nice too =)
