I planned to dinner with friends at Eastwood at 6.30pm. I left home around 5.30pm. An hour time, it should be enough. But I spent 15 min for lining up to buy a ticket. Then I missed a train. That should be only a bit late. I need to wait for the other one on next 10 min. Moreover, the train was late. That was around 5 min to 10 min late. I have spent around extra 30 min. OK, I missed the dinner! I put more more extra time next times.
