We all manage our days differently. I'm out all day with the toddler and baby so I don't have to clean as much when I get home. Until I learned that, I spent most of my evening cleaning.
I now clean on the go, every time a plate is dirty, a side has crumbs on, a sink has beard trimmings on, it's sorted immediately but my family constantly undermine my efforts. That makes it harder for me than someone who lives with a tidier spouse and easier than someone who has a messier spouse.
I am simplifying my life, I have fewer plants to tend, less clutter than I had, fewer social engagements. It all adds up to steal precious time.
I enjoy cooking from scratch, it takes time to prepare and to clean up. I have less time than someone who pops in chips and nuggets.
We get ill a lot. I never used to but for some reason now we all do. (gross toddlers probably).
My family takes up my time - around 4 full days a month, because they're far away. They don't help with the kids, we just have to visit them and lose half of our weekends a month.
We manage my mil from afar - her finances, when she gets scam calls, ordering her food shopping etc.
These all sound small but add it all up and it makes a big difference. We all have different sleep needs, energy levels and different things on our plate. Some of us have our sh1t together, some of us overcomplicate life and have less time.
I love to read BTW and it sounds like you're being judged for having time, not for reading. Try and remember, life genuinely is busier for some people than others.
