Mercury is retrograde in Sagittarius, so check out which house it is affecting in your chart. That's where you'll need to think about making some changes and/or tie up loose ends. Sagittarius is the sign associated with seeking higher knowledge. Ask yourself if you are only seeing the surface of an issue and need to dig deeper.
I was checking out April's blog (thanks for the link!) and she wrote about Mercury's shadow period. During the shadow period, I attempted to cook something in the stove. It was supposed to take half an hour. After the first half hour, I realized a fuse was blown in the stove. So I replace it. Half an hour later, I realize I replaced it with a blown out fuse and there are no more to be found. The next hour I try to cook using only half the stove. Then I gave up and just ate it anyway. It was cooked well enough. No food poisoning so I say it worked out pretty good considering. Lesson: If your stove needs fuses stock up LOL. Needless to say, Mercury affects appliances.
