Why Cry Over Spilled Milk?

I'm a little upset with "Genius". He cancelled our date for today. He was held up because of business. However, he wants to see me tomorrow but I told him, "No, I have plans". I'm not going to reschedule my plans for anyone anymore. I also have plans to see a "few good men" in the next few days so I really could care less about "Genius".  I'm going to keep moving forward. When "Genius" learns his lesson and emails me again, I may give him another chance.
