Yes, on monday and tuesday you feel very deep and intellectual, and you may talk at length about your opinions, but your travel partners could get annoyed: so tone it down. Starting late afternoon tuesday, there's an undercurrent of confusion among all of you. Things calm down thursday night, when something you attend alters your opinion. A new person you meet may also be the driving force behind this radical change. Late saturday and sunday your thoughts about this new idea may become blurry and cloudy. Write, draw or paint, or do something else creative to get your mind off of it.
