Goodbye to the old Facebook account of my past social media self. Filled with old edited pictures through Picnik, dramatic song lyrics as captions, and symbol letter writing. Updated posts each hour of my constant activities for that moment, tagging each individual friend I was with, and telling everyone about the smallest details of my experiences that I dramatized to make it seem funner than they were. It was all too obnoxious for the social media of a thirteen year old.
I agree as I go back to my first posts on both Instagram and Facebook, I have a similar experience to what you describe here.
I also relate to your first social media self. I remember when I would spend hours editing pictures and finding dramatic quotes to use as a caption!
