I just checked my calendar for tomorrow, and realized my Nikon class at Wolf Camera is in the morning. Yay! Except I haven't paid for it yet. So, do I stick to my plan and not spend the cash, or do I violate my own rules that I laid out only two days ago? Yeah, the camera wins. I will go to the class.
BUT! I'm returning a shirt I bought a couple weeks ago, which will help offset that cost.
Oh, well. Exception #1. Let's hope that's the first and last!
