My coworker came over to my desk and asked if I had time to meet for about a half-hour the next day. My calendar happened to be open on my desktop. I consulted it with a long look and said, "Ahh, it looks like I have a half-hour I can get together around 3 tomorrow." She stood looking over my shoulder and said, "Let's say 2 o'clock," and she walked away. So I turned to my boss and asked, "What day is it today?" It's tough to schedule a meeting for tomorrow when you have no idea what today is.
