If you need to cry on command, thinking of a time when you felt sad can help put you in the right frame of mind for tears. For example, it may  help to think back to the loss of a loved one or a particularly bad breakup. Other emotional triggers might include losing something special to you, getting in trouble with your parents, or missing out on something you worked really hard to achieve. Many people have fears that deep down they are not as strong as they like to believe. Picturing yourself as small and weak might put you in a vulnerable mindset that can lead to real tears.  Once you tap into that feeling, let the helpless feeling flow out of you in the fear of tears. For example, a common exercise in acting classes is to imagine yourself as a small child whom no one cares for. Sometimes, thinking back on a bad experience from the past can lead to real emotions that are hard to overcome. If this is the case, try to imagine something sad that could happen hypothetically rather than thinking of something personal. For instance, you could try thinking of puppies being left on the side of the road. You want to save them all, but you can only take one. As you're holding the one puppy you got to save, you look at all of the other puppies that aren't being held. Try imagining things that make your eyes fill up with happy tears, like a time someone gave you a meaningful gift, veterans being reunited with their families, or someone triumphing in the face of adversity. As long as you’re not smiling, no one will be able to tell if you’re crying happy or sad tears.
