You have the luck of being Dick Grayson aka Nightwings roommate,You don't really question what he does much

Its late at night about 2:00AM and you are sitting on the couch in the living room watching some dumb chick flick until you hear the front door open

You turn to look at the door and see your roommate adorning his Nightwing costume with a small gray pitbull in his arms "Oh!,Youre up" He smiles sheepishly as the dog licks his face
