What do people do in the evenings?

My Swiss roommate leaves for work before 6am in the morning because she doesn’t want to get home too late. But by the time she gets home usually at 6pm (long commute), she’s so pooped she spends the next 2 hours with the TV on scrolling on TikTok before going to bed at 9pm so she can start her day early again next morning. I’m just curious what people in their late 20s/early30s do after work?
