At the end of December, my wife announced she was taking me out for an early birthday surprise. I was given no information except that I could dress casual, and that I should be ready to leave the house at a very specific date and time. As we headed out towards an unknown destination, I started trying to guess the surprise. I had previously announced that I really wanted to get a keyboard, but she didn’t know the specific model (plus every store nearby was out of stock due to holiday demand).
