my dearest T-Cells,
I am truly grateful for all of the work you’ve done to keep me alive.  I know you guys work hard to identify and destroy any foreign infections and I’m really grateful.  However, I’d like to clear up a little misunderstanding: the myelin sheath around my brain and nerves isn’t a threat.  It’s just there to keep the electrical signals flowing through my nerves right.  I know, myelin is tasty, but, it’s really time to stop eating it.  I need it so my hands and feet will work.  If you let me know where the misunderstanding started, I’ll clear it up, but for now, just go back to fighting the bad guys.
the rest of you
