Sara: I'd like your permission to use you as a professional reference. Would that be alright with you?
Me: Sure. Feel free to use this email address and my cell number for contact info. My address will be changing, but that probably won't matter anyway, since nobody really sends mail anymore ...
Sara: Thanks! I hope mail goes the way of the Coelacanth.
Me (after a little Googling): Sweet dinofish reference, Bro.
