Weekends are the days, when everyone can relax. I do the same. I always decide where to go, but I often can stay at home and play chess with my older brother. We like to spend our weekends together and we also like to walk to the park. Breathing the fresh air for two hours is necessarily for us. Then we go back, have a dinner and get up for visiting the theatre. My mom is fond of theatre, so we often go to see an interesting play there. After finishing the play we back to home. After supper I always read and then go to bed.

Professions are jobs that people have. Like doctors, for example. There are different kinds of doctors. If someone has a sickness, doesn't have to be a specific one, they come to a doctor. Another profession is a business man. There are loads of different ones. Some have a website of their own, some have ads all over the internet. Most of the time, they make lots of money and have other people recruited for the job.

Glad to help :)
I know all of this because I'm from England myself. I moved to Moscow 2 years ago and learned Russian, so I'm on this website now haha.
