Well I enjoyed your post before you deleted it.
Same.
I almost wonder if she planned on deleting it before posting it in the first place.
I don't think so. It gave a very open comfortable vibe like she was casually sharing her day with friends. And she left it up until Xad said whatever he said before changing his comment. I think whatever he said made her feel embarrassed so she deleted it.
She's a wicked suspicious character though, far from innocent. It's worth treating her actions as if they had potential prior intentions as opposed to a naive "oopsie".
what did she write, can you please summarise?
Nothing out of the ordinary for her. Posted a filtered selfie, a picture of her cat, some pop music, and narrated her daily goings-on in between some vaguely wistful ramblings about herself.
