I actually asked the person I'm as of yet still stuck on if she'd actually miss me or wouldn't even notice, she said the former but I know it's a lie since opening our chat (which I try not to do) reminded me that she stopped responding. Most "friends" won't be the wiser since they wouldn't have texted anyways and my parents won't know who they are to inform them. Plus if any of my "notes" (re: literal bullet notes at this point) are followed then none of those people would be notified anyways. I'm such a person that for most people it becomes a relief when I stop writing. I doubt many would question if I disappeared, they'd just quietly enjoy the absence and move on.
I think some of the great people on here are much more likely to notice than some people I had known for years. Who I was supposedly special to.
