A long, long time ago (maybe 2002?), these two kids went to the Shedd Aquarium. Pre-kids, of course. In fact, they had only been dating about a year. (If you don't count the break someone thought he needed. *insert eye roll*)
The girl bought a cute little-penguins-dancing-in-water keepsake, which she kept on her desk at work for many years. Until she moved to a new building and her office had a window.
But (to sadly quote Metallica *insert even larger eye roll here as the girl hates the band*), the memory remains.
