Why didnt you go for a walk in the morning as usual?
It was raining very heavily in the morning. The weather was windy and cold and I stayed at home. After lunch, when it was still raining outside, my sister and I decided to make a cake with strawberry jam. It took us about an hour to make the cake. When it was ready, I called my neighbour Sergey (we are very good friends) to have tea with us. We had a very nice afternoon and the cake was delicious!
