Dear Ben,
Thank you for your letter. Sorry for not writing for so long. You asked me about job.
To be honest, last summer I tried find any job to get some pocket money. I worked as a promoter. Of course, this job was not so interesting, but I got enough money for my entertainment.
In our country schoolchildren usually have from 100 to 500 rubles. It is enough for schoolchildren. They can spend pocket money on theirselves and do different things such as visiting museums or they can go to the cinema with their friends or just have a great time.
Sorry, my mum is calling me. Drop me a line.
Yours,
(твое имя)
