I'm the same.
I don't get the "On MN, it's normal, In real life, it's weird," comments. So, people who post on MN aren't real people living real lives? Odd comment.
I don't like unannounced visitors. If people are going to come around, I'd prefer to have a specific time when they're doing so. If not, I just end up feeling like I have to wait around all day for them and don't feel comfortable getting in the middle of something i.e. a book, a movie or a meal or whatever because it could get interrupted at any minute.
I am an introvert, though and when I'm chilling, I like to be "switched off." I don't like to be on edge, thinking when I'm going to have to "switch on."
There's a few posters on here who clearly fall on the more extrovert side of the spectrum and that's ok, but some of the comments here fall into the "lack empathy and understanding that not everyone is like me and likes/appreciates impromptu visits."
I would be willing to bet that they're likely the sort that deliver impromptu visits to their friends and their friends may be too polite to tell them that they don't always appreciate it.
I also like to slob around in my PJs all day if I've nowhere to go and no one to see and I don't care. Of course-you had to cue the "Oh, I could never sit around in my PJs all day-gross!" comments! 😆
