I can genuinely never tell if it's, like, a piece of food that didn't get swallowed, or something that spawns in my throat as some latent curse from that time I had strep throat and got a partial tonsillectomy. One time I did have some disgusting buildup back there which I just kinda squeezed out and was done with so it might be related to that.
one thing that's really cool about libreoffice writer which I'm probably never going to use is you can just. move a heading and the entire section will follow. no need to copy paste. good for like essays I guess if you need to reorder some stuff for whatever reason. I guess if I write some kinda flashback chapter or intermissions I can like find the right spot for that but lol probably not. it's a really neat feature tho
