I'm not a party person. My sensory issues make it especially difficult for me to hear/process anything people say if there is music playing in the background, and thumping bass is a very strong sensory/meltdown trigger for me. I'm also older than the age groups nightclubs are geared toward, and I don't really like the meat-market atmosphere and the often sexually aggressive drunks in bars. Also, I live in a smallish town in a mostly rural area, so while there are many bars, night clubs are all about an hour's drive away.
Really, I'd far rather spend my Friday or Saturday night watching horror movies, drawing, noodling around online, or even working, since I like my job. As to the rest of the weekend... Well, as far as I'm concerned, Sundays exist solely for sleeping in, hanging around the house in PJs all day, curling up with a good book, and spending quality time with the family and the pets. I don't set foot outside the house on Sundays if I can help it. Granted, it's also my major laundry and tidy-up day too.
