1. A true friend is not just the one who can sympathize when you are down, but also and especially the one who can be happy for you, when you are happy.
2. Friends do not give advice, they help you to decide.
3. True friends doesn't crticise, but instead finds positives in a way that you know what and how to improve.
4. There is no such thing as a "true friend". There is just "friend". When any other words are added to the meaning of say "true love" (is there untrue love?), "true friend" (OK friend?) that can mean anything, but not the friend or love.
Dear Mr and Mrs Browns,
I'm writing to you because I want to thank you for those fantactic holidays I spent with you in London. Thanks for giving me the room, which was very big and neat and the view from the window was great. Mrs Brown, you are a magnificent cooker. The food was delicious. Thanks for the excursions you organised for me because I learnt many new interesring things about London. I liked Buckingham Palace most of all. I was deeply impressed by your hospitality. During that week I improved my English a lot. Now I'm not afraid of speaking English with people and for me it is a great step forward. I thank you kindly for the amazing time I spent in your friendly family. Now, it is my turn to invite you to my place. I invite you to visit Moscow and I hope, you will spend time learning many interesting things about Russian capital.
Hope to see you at my place next summer!
Do agree and come! You are welcome.
Keep in touch.
Best wishes,
Alina
