How nice to hear from you again. I was delighted to receive your letter.

Let me tell you something about the recent changes in our city.

The new traffic regulations have definitely improved the flow of cars, but they have also caused some inconvenience for pedestrians. For instance, the new crossing signals are not clearly visible, which has led to several near-misses.

I believe that if we can improve the public transportation system, it would help mitigate these issues. Perhaps we could invest in better signage and increase the frequency of buses and trains.

I look forward to hearing your thoughts on this matter. Best regards, [Your Name].
