Sample of the BEM Paper

There are so many cars on the roads nowadays that driving in big
towns is not pleasant at all.
Some time ago, a friend who works in a part of the city I do not
know very well, invited me. It took me hours to get there and
find a place to park. As I was late, I hurried off on foot, thinking
that these days it is much easier to walk than to drive. At noon, just
as I was leaving my friend’s office, I suddenly realised that I had no
idea where I had parked my car. I walked down street after street,
examining each car closely but without any result. Feeling quite tired, I
gave up the search and went off for lunch. Some time later, I left the
restaurant and walked slowly down the street. I turned the corner, and
there was my car, right in front of me but on the ****** was a little
ticket. It was a fine for bad parking.
Next time I visit my friend, I’ll take a taxi.
