Not sure as these sentences make little sense 😀
na oko means approximetly
Are you asking whether you need to use personal pronoun in a sentence?
No, you don't need to, both Mieszkam i Ja mieszkam are correct.
I wasn't even considering a personal pronoun. I know that those sentences make little sense but they made sense to me at the time I came up with them... :) thanks for the answer
I understand, not a problem.
Please feel free to ask more questions about Polish language, I will be very happy to help 😀
