Welp, I deleted my Facebook account when I was 11.
But there wasn't anything special anyway. I just used to post photos of flowers, butterflies, water reflections, etc. that I took.

I did post one weird video though. I took a couple pictures of someone's smashed window and the glass on ground. Then I made a slideshow edit of that with the song Yesterday by Beatles in app called Picmotion. I was around 9 when I made that. I am still not sure why.
