"This is your life" skit----
we needed to come up with people from her past--- one of her uncles came, a teacher she worked with long ago, a teacher that had both of her sons (now retired), etc...
They were behind a curtain and said some awfully nice things about her and then came out to reveal who they were- I think she knew the voices!
I had to cry when her uncle was talking ---it was just so sweet.
I hope this is another idea for you
