Have I become one of "those" people?

For the first time in my life, I have brought work home with me. I am not happy that I have broke my pact to myself, but here I am.
I have three reviews that I have to complete on my employees. The only way to get these done on time, was to bring them home.
It is allready affecting my Saturday. I am half way through Casablanca and would really like to finish it, I have books to read, naps to take, coffee to drink, people to visit, but this "work" I have brought home is laying there mocking me.
It is pissing me off. I have allowed my corporate job to seep into my personal time. This is so against my principle, which leads me to the realization that my ideas and principles may be shifting a little. Does this happen with age? with maturity? with a corporate job?
I'm not sure, but I do know I am going to go make a latte, and then dig into my employee's reviews. So, while they are off enjoying their weekend, I will be evaluating their work perfomance and contemplating my own......
