Sour coffee?

Sounds disgusting, right? Don't worry, it is. I guess I just felt guilty throwing out a perfectly good cup of coffee, and since it was still in the pot from yesterday, it was a cinch to reheat. (The fact that it was Starbucks Christmas Blend made me even more hesitant to dispose of it.) So I did just that -- reheated it, poured myself a cup and sat down with some peanut butter cup bars thinking it would be the perfect mid-morning treat after chasing an energy infused Oliver since the moment I opened my eyes today. What a major disappointment. I could hardly enjoy my bar because I was washing it down with nastiness. I kept thinking I would be surprised and the next sip of coffee wouldn't be as bad as I thought..nope, worse. Yuck.
