Oh, come on. You really don't think, at some point, every leader has been caught looking the other way, or talking to someone, or waving to someone, or with their eyes shut in one of these big group photos?
Our PM missed a major group shot a while ago because he was in the washroom. LOL.
Just like that adolescent behind another family member when a family photo is being taken. You know the one, it is the kid that stands behind someone and raises his pinky and index fingers to form devil horns.
