As others have said, tidying and cleaning are quite different things. Most cleaners will come to do the latter. If your house is untidy, it makes their job harder.
You can get a person in to tidy up for you, but it’s usually a different person than the cleaner, and that requires much more input from yourself “Where does this go? Where do you want this? Do these clothes need to be folded or washed? Is this trash or not?”.
Anyway. Yes I’ve definitely been guilty of tidying the whole house before our cleaner comes.
Same. People age quite differently. I didn’t start puberty until I was 16. I didn’t get attracted to girls until I was 17. Much later than my friends.
I got a job at a pizza shop when I was 20, and I made friends with the 15+16yo employees there, I got along much better with them than people my own age. I can see how that’s was potentially creepy, looking back on it, but it seemed normal enough at the time, those people were my good friends.
I matured very slowly. I didn’t graduate uni until I was 29. I’m now 39, physically I look like I’m 30, mentally and psychologically I feel like I’m 30.
