Thank you. I've mentioned before that I've never used facebook.
Would you know if that was a picture she sought out to post, or if someone else sent it to her and she was liking / copying / sharing it in her group?
Usually a meme like this is shared by someone you know, or shared in a group you are in, and then you like it, you find it funny, it touches you in some way, and you decide to share it with your friends on your page.
KW shared this on her page with her friends, but she found it somewhere else, and we have no way to know where she saw it.
I find it quite unusual to be able to seek out and find the perfect meme at the right time to make a correlatory assertion about a meme, and I find their use extremely prejudicial when used in trials. In the trial for the murder of Bella Bond, the mom had previously shared a meme that said something like "don't cross me, because I know where to bury a body!" Millions of people on FB would have shared that meme and it has zero correlation to the people sharing it being murderers.
I would have interpreted that meme to touch most people in the sense of a breakup of a relationship, and that a lot of people sharing it might be thinking of it in those terms. We have no way of knowing how and why that meme 'touched' KW in the moment when she shared it. It could go to frame of mind if we knew 100% what happened in her life that day or just prior, but we don't know that.
