В прошлом году учили как их писать, в общем, попробую вспомнить) :
Unpredictable meeting(название, вроде обязательно должно быть)
Suddenly I heard a knock at the door. I was a little bit scared, because I didn't know who knocked. I hadn't waited for guests. I had a lot of thought in my head about who it could be.
I decided to open the door. During my walking to the door I was having the worst variants of future development of events. Не I scrolled the key and opened the door. I couldn't believe that, the man stayed in front of me. We kept silence for about a 2 minutes and than I invited him to come in.
It was my father, whom I lost 4 years ago. We had a cup of tea and talked. He said me that he got in some troubles and couldn't meet with me. He apologized, but I wasn't angree, I knew, that he couldn't leave me without a reason. It was the best meeting for 4 years.
