It's now not unusual to prepare for a visit and even several visits to your relatives and friends on the same day, while in the past this may have taken several weeks or months. However, despite all that, I still see some failings in the development of the means of interaction. For instance, the very high cost each person spends every day on communication. Another defect, many elder people are not accustomed to this modern technology.But that doesn't have a great effect on the positive role technology has made in the field of interaction between people,and I think these defects are very easy to be solved.
