Private Education
We all want the best education possible for our children. For some people, that means that they are able and willing to pay for private education in hopes of giving your child supposable advantages. But sometimes, not even an elite and private education can help people from making spelling mistakes.
Or, you know, help them from retaining the information and knowledge shared with them during their school years. Perhaps this parent could have kept their child in private education, but it is not given that the child would be able to avoid similar mistakes.
