For teens, it may be a want and a need. If I self-analyze myself, I realize that my phone allows me to keep in contact with my friends and especially, my family. When I need to be picked up from school, I call my parents. I also realize most of my phone isn't being used to call my parents. I look at social media and I play silly games which are not a need.
   For mothers, most believe that technology is very helpful. These days there are applications that can help with diets and exercise. They also might think that using their phone is a good way to distract their loud child in a restaurant. Using a phone to distract a child can be good and bad. It may be good if the child stops whining, but if a mother continuously uses the phone to keep the child busy, she is preventing the child from having a good connection with the mother.
