Another cup--Why not.
I think drinking coffee is kind of like a cigarette chain smoker. It just feels like it needs to be next to you,always ready when you are. And in the case of a cup of coffee, you have to drink it before it goes cold.
There are others times however when you really want to stop and enjoy coffee slowly. These are those special moments. This, in my case is my espresso moments or moments to try something totally different. A time to experiment and see if there is anything better. I think you will never know until you try them all.
But there is more to coffee than just great taste. The whole culture of coffee has always been interesting to me. Therefore, I often read about coffee as well. The total experience is what makes me what i am--a true coffee lover.
