A few years ago, when I was a student, I arranged to meet a friend who was visiting London for a weekend. Unfortunately, I forgot to ask him on every important thing — the full name and address of his hotel. I didn\'t have any way to contact him, so I just decided to look for him in the busiest street in the city! What was I thinking? Anyway, I was beginning to give up when — you`ve guessed it — I looked up and saw my friend. He was walking straight towards me, with a big smile on his face.
