Okay, this is how I picture the preparation for the special evening.

Bridget's date comes to pick her up. As the family gathers with her and the date in the living room, Bridget says, "We need to take pictures before we go." Mom gets the camera and Bridget goes over to the couch where she and Daisy cuddle together as mom snaps away. Bridget's date stands there wondering where he went wrong.
