Dear Ben,
I can't imagine life without my computer either. I use it for study and work: writing essays, doing online research, checking my email, and watching educational videos. I also practise languages with online tutors and organize my notes.
I usually spend about 2 hours a day on school work on the computer, sometimes a bit more when assignments are due.
In my free time I read novels, play the guitar, go for runs, and chat with friends online. I also enjoy photography and sometimes play online games with my cousins.
What about you? Write back soon.
Best wishes, Sam
