The price for the part a person needs for their computer going up 10% right before they decide to buy it is not a good thing because it means that they will have to spend more money than they originally planned to.
Consider the statement "A part for my computer that I've been putting off buying went up 10% right before I finally ordered it.". Is the statement "The fact that the price for the part I need for my computer went up 10% right before I decided to buy it made me pleased" false? Yes/no/unknown
