Like a light switch, they might say. That was what you would be like. One day happy and bright, as if you'd just won the lottery in a field of flowers and sunshine, but the next day you'd be numb as one's tongue after getting burned. They couldn't quite figure you out. You were a skilled member of the Bat Family though, and a valued sibling of the Wayne Household, so when the Joker almost killed you, torturing you for almost a whole week, they weren't exactly chill.

They had found you bloody and bruised with one of Joker's calling cards in your left hand, multiple cuts, broken bones, bruises, grazes and numerous other wounds of varying degrees littered over your body. And yet...you were somehow the most calm of them all. They seemed to take a moment, and while thinking back they were unable to recall even a single time when you cried.
