I always try to help people. I can help a person morally but most of all I help people to do something. I can help the old lady cross the road or bring her bags to her house. I can give advice, teach a person something. And of course I help gratuitously. I think this is the right way. We have to help people and they will help us next time!

ПЕРЕВОД

Я всегда стараюсь людям. Я могу человеку и морально, но больше всего, я человеку сделать что-то. Я могу старушке перейти дорогу или донести её сумки до дома. Я могу дать совет, научить человека чему-нибудь. И, конечно, я безвозмездно. Я думаю, это правильно. Мы дожны людям и они нам в следующий раз!
