a) At last I got to the station; actually this morning I had gotten some troubles; my friend who always picked me up going to office was sick, in fact I had waited for her very long but she still didn’t come and finally I phoned her and she said that she was sick so she couldn’t work today. After that I decided to go by a taxi to the station because by train could be faster than a taxi to reach my office, but I waited for a taxi very long too. I thought actually I had waited for two things that spent much time. Ten minutes later, finally I arrived in this station but when I wanted to buy a ticket, the ticket had been sold out for ten minutes ago. I was very disappointed, if I had arrived ten minutes earlier, I should have caught the train.
