Despite mankind's grudging acceptance of the fact people age as time passes, pictorial evidence that a child from a popular television show has grown up tends to send the internet into a frenzy and leaves fans suddenly feeling far too old.
On Monday, a photo of the now former child actors from the hit comedy series Outnumbered began circulating on social media.
The popular BBC show ran from 2007 to 2014 and documented a chaotic household comprising of three children: Jake, Karen and Ben and their (outnumbered) parents played by comedian Hugh Dennis and the actress Claire Skinner.
The photo, which was taken at a lunch they had together on Sunday, shows Tyger Drew-Honey, 20, who played the eldest sibling Jake, Ramona Maquez, 15, who played Karen and Daniel Roche, 16, who played Ben reunited.
Fans immediately shared their shock and horror on Twitter:
Others chose to react to the news differently:
Drew-Honey, who has embarked on a successful presenting career since the show, re-tweeted a shocked message from a fan and said he was surprised how much the photo had taken off.
A one-off special of Outnumbered is being filmed later this year.
