It all changed when...I went from working in the city to commuting to Connecticut, and then back to working in the city.
It all changed when...the Charlie Brown holiday specials came out on video, meaning that you could watch The Great Pumpkin any day of the year, not just on a long-awaited night in October.
It all changed when...I discovered the trains that go diagonally, not just uptown and downtown.
It all changed...when my "day" became night and my "night" became day.
It all changed...when the givens were taken away and new takeaways became the given.
It all changed...well, every day. Because that's what things do--they change. Lucky for us, we get to change with them.
