Ill put it to you like I put it to the guests at my wedding who watched me usher two "wedding crashers" out of our event and subsequently head first into a wall just outside our venue. The folks might be really nice people, but I do not know who they are or what their intentions are. They were kindly asked to leave first, but on the first "Why?" reply it was time for them to go. Like with this kid, you have no idea what they are thinking of doing. What may appear funny/cute/whatever, may be a plot for something much sinister.
