> You just behave like a normal person.

?? I'm a normal person, and I don't need to count my days in and out of a country, I just take vacations when I like.

If OP did that, they'd lose their visa.

It sounds like you've never known anyone on a green card, or waiting for citizenship, or on a visa that requires a certain number of days in the country.

> To apply for British citizenship, you need to prove you were physically in the UK on your application date but five years ago.

This is an insane bureaucratic requirement (to have been in the country exactly 5 years on the day prior), and not someone the vast majority of people need to worry about. How does "just behave like a normal person" help keep you on the right side of multiple overlapping Kafkaesque requirements?
