She will use a program call line vdo. The mother and father use a program line is so close and talk together, and be able to talk to each other at any time because of the ease and fast. There are a lot of tricks from the telephone talk, because there is more costly. Cause sometimes it feels a little small and the mother did not call? But by sending a message through a single pipeline.
