Craving violin strings on my finger tips.  That sharp straight pain that just melts into music.  Usually in the quiet of the morning I think of it most.... it's also when I definitely can't pull it out unless just to hold it, slide my fingers from position to position in my unsteady and unsure way. 

Someday, at 7am, I will pull it out and play away.... though that day is probably a VERY long way away.  ;) 

Is that a viola?  Might be.
