You say that Lisa is your best friend but that is actually true you should know every small thing about her. Here we are going to be testing your claims of being her best friend. We will show two similar pictures of Lisa. One image will be original while the other will be a forged copy. If you are indeed her best friend you should be able to tell all the differences between the two pictures that you see. For each pair of pictures that we display on your screen and ask you to find the differences we will be giving you limited time.
