Thanks for your letter. It was great to hear from you again. I’m proud that you do a big favor for your family, helping your parents with household chores. Unfortunately, I can’t brag about a long list of family responsibilities, which I do. I usually do easy tasks such as washing the dishes and bringing things. As for shopping, we always go to the mall together at the weekends. It’s the greatest way to spend time with family and enjoy shopping. Besides this, when we have some free time, we go to a café at the center of Rostov, where we spend our time with joy and fun!
