As school starts again, there's so much more for an American parent to nag （唠叨）about, like homework，bedtime and lost hours on the Internet.
But in the age of digital childhood，Jacky Longwell, 45 , of McLean, Virginia, often text – messages what she once told her children by mouth: Be nice to your brother; walk the dog; remember your reading.
This is the world of the modern family, in which even reminding children to do something has become electronic.
There are changes in how parents nag and in what they nag about and in how often of their nagging.
With technology," you nag more, and you are a little bit more precise （其体的）with your nagging,” said Reginald Black, 46, of Woodbridge. Virginia.
For many young people electronic nagging is part of the experience of growing up.
Charles Flowers, 17, a senior at St. John’s College High School in Washington, says his mother reminds him about everything from laundry, being on time to baseball practice and mowing the lawn by text.
When she uses capitals he knows she’s serious: GET HOME!
Some say technology has made nagging less annoying. Jacky Longwell thinks texts are less emotional than spoken messages and less likely to be resisted by teenagers.
“It’s not as painful for them to hear it by text. It becomes grouped with the friendly communication.” she said. “They can’t hear the nagging.”
She thinks a good way to do it is to mix friendliness with nagging. A parent can always start by saying hello.
Not all parents like the new electronic nagging. Joyce Bouchard, 51, a mother of four in Fairfax, Virginia , texts her 14 - year - old son but says that for many things-chores, homework-the old - fashioned way works better. Nagging by text has risks. She notes: “I always think, if you’re texting them something and they’re with their friends, they are getting a big laugh out of it.”
