Really, I do not understand why you want to make you look like you have cried. Nevertheless, I have some ways to help you to realize your dream. That is to say, you can use some mascara on your eyelashes, later you can just rub your eyes a little, then your eyes will be filled with water and you will look like you have cried. Besides, you can just make it by yourself; without any help from others—just do not blink your eyes for long time, and then your eyes will be filled with water automatically. Oh, I just remember that there is another useful ways because I have tried to cheat my mother. :) You can go to your bathroom and turn on the hot water and close the door, and then pls see the water condense on the walls of the house. As a matter of the fact, the humid temperature and the corresponding condensation may help you to look like you have cried. Hope my suggestion can help you make it.
