history: I'm thankful for my old elementary school principal.  Hope she's doing well wherever she is.  She saved me from drowning when I was in 1st grade My old elementary school principal saved me from drowning when I was in 1st grade.  I'm eternally thankful for her and hope she's doing well wherever she is now thats an amazing memory to have_comma_ have you since visited her or sent her a card? 
current: That's a great idea but I don't know where she lives
next: I would call the school and see if they can disclose that or maybe they can accept the card from you to give to her!
