Sadness is one of the five emotions inside the mind of Riley Andersen. Sadness would love to be more optimistic and helpful in keeping Riley happy, but she finds it so hard to be positive. Sometimes it seems like the best thing to do is just lie on the floor and have a good cry. Sadness is literally the very definition and being of sorrow and gloom. She is hardly ever used because Joy is the boss and doesn't want Riley to ever be sad, even when she needs to be. She is the most sensitive out of all the emotions.
If possible, lie on the ground and pose as if you’re crying. For Sadness, it sometimes seems the best thing to just lie on the floor and have a good cry.
