Sometimes to work on homework, sometimes to read and sometimes just to think.
You overused "sometimes" in here, you could instead write:
"Sometimes to work on homework, read and just to think."
Other than that, it was fine and good.
I'm pretty sure I did it on purpose.
A lot of the sentences also start at odd parts, which was also on purpose. I was reading a lot of Jane Austen at the time.
I see, but I must tell that I was taught at school to never overuse a word, it makes a sentence sloppy or something.
