Вот тебе одно
Dear Edward,
Thank you for your letter. Sorry I couldn’t write you back earlier.
I totally understand your position about pocket money and the way you want to spend them, because I’ve got a similar situation or even worse: my parents never give me any money for doing some housework. They only give me some everyday money to take lunch at school and some extra-money before holydays. And I should say, that it’s not much at all. Usually I try to save up enough money to buy some closes of jewelry. And my parents think that it’s a regular way to spend money for a teenager.
Anyway, you've mentioned a picnic. How was it by the way? Did you have fun? Were there a lot of people?
I've got to go as my father is asking me to help him with his car.
Write back soon,
Best wishes,
Johny
