A tiff with a colleague on monday or tuesday is probably nothing personal. Let it go, and make an overture to show that you're doing so. Beware of the potential for those around you to misinterpret your directions or ideas midweek. Forewarned is forearmed, though; if you're extra clear, it can all go extra well. Sometime after thursday, a certain party's got a different take on a budget or other monetary matter than you do, and you might feel that they're implicitly criticizing your numbers or concept. Try responding with your intellect rather than your feelings.
