This is an actual newspaper clipping I found when we lived in Nairobi. For the main newspaper for a city of about 3 million people, I consider that to be unacceptable.
Lest I be too quick to judge, I must remind myself that I have made mistakes too.
A small takeaway for you – I have found it worth hitting the “Preview” button before I publish a post on this website. I have caught several mistakes I would have otherwise missed!
