If you'd asked me a few days ago if my young son XiXi had any clue how to record a video on my phone, I would have said no, certainly not. He's five. He's not allowed to use my phone. He probably doesn't even know that my phone can record videos.
Then I saw something on my camera roll. Something I hadn't put there. And now I stand corrected. Yes, my son does know how to record a video on my phone. And I'm so very glad that he somehow gained this knowledge because his 20 second video is now my favorite. Pretty much ever.
