You will hear my comment very sad, but I wish in Mexico there would not be so much violence, so that I could go out for a walk calmly and not worry because at any moment you could be kidnapped, raped, harassed, sexually abused.
When I went to Canada for a few months to learn a little English, I went for a walk every day, it was incredible and it was really what I enjoyed the most of the trip. By not worrying about something being done to you, you enjoy the walk and the scenery.
