Maybe I've lost my mind, but I just spent $10 on batteries for a 14 year old calculator. I could buy a brand new calculator for less than $10, but it wouldn't be my trusty hp28s that I struggled to learn RPN on 14 years ago.
I hope one day that I will be as attached to my CD Gulfstream, as I am to this calculator. I have rolling instruction at an indoor pool scheduled for the 26th of February with Black Parrot Paddling. If I struggle as much learning how to roll as I did learning RPN, I may indeed be permantly bonded to my Gulfstream.
