Anyone who's tried to wrangle their young children for a family photo—or even a non-chaotic trip to Target—has likely marveled at the impeccable behavior of Kate Middleton and Prince William's three kids, all of whom are required to attend more official state events in a month than most of us will attend over a lifetime. That's why the Together At Christmas carol service at Westminster Abbey was so refreshing, as there we saw five-year-old Prince Louis behave like an actual five-year-old.

This was the third year in a row that the Princess of Wales has hosted the annual event, a special Christmas carol service founded by Middleton that—this year—included carols from the Westminster Abbey choir, as well as celebrity performers including singers Beverley Knight and Adam Lambert and actors Leonie Elliott, Jim Broadbent, and Micheal Ward. Middleton's family, including William, Louis, and older kids Prince George (age 10) and Princess Charlotte (age eight) were also front and center at Friday's taping of the event, which will be broadcast in the U.K. on Christmas Eve.

The two-hour-long ceremony would have been enough to try many folks' souls, let alone a Year One (that's kindergarten to those of us in the States) kid. Louis was reportedly sleepy during the service, and was caught yawning by Today. 

His flagging energy was revived, however, when fire was introduced to the picture. As captured on camera, Louis's excitement at the prospect of flames prompted him to try to blow out his sister's candle, a move that prompted Charlotte to let loose with a grin—and his mother to pull an exasperated face familiar to anyone who's tried to keep their kids in line in public.

Louis has become a favorite of photographers in recent months, simply for being more expressive than the other members of his immediate family. His animation was noted during King Charles's coronation, as was his excitement at this summer's steamy Trooping the Colour.

The delight folks find in Louis's normal human child behavior might be a solid note for the family, which is battling rumors of cold, stiff behavior. Perhaps allowing the facade of perfection to slip, just a bit, to reveal the real people beneath would be of benefit? If nothing else, seeing the Wales's children behave childishly now would be a better look than childish behavior (or worse) as an adult
