In the West they hover and swoop. In Japan they stalk and are known to strike. We all have them and some of us have been them. And in recent years the media, both social and antisocial, have put them under the magnifying glass of criticism.
They — or we — are parents. To be specific, helicopter parents in the English-speaking world; monsutā pearento, or monster parents, to the Japanese. These are the mothers and fathers of CWKs (Closely Watched Kids). The Chinese call them monster parents too. Leave it to them to have their own website: monsterparent.com. In Korea the situation is so bad that some parents don't know the difference between a diploma and a diaper.
In this day and age of technological surveillance, perhaps the term Drone Parents would be more appropriate. They monitor not only the movements and behavior of their children but also the treatment given them by teachers.
