I dont like it either and will only use it under rare circumstances. It takes forever to type a normal length message out. Id rather just call someone or send an email.
My youngest just won't answer the cell phone when I call most of the time. He'll only respond to texts, and does so promptly. His friends are the same way. It's a generational thing, just have to get used to it.
Um, who's the parent here? How young is this youngest you are speaking of?
Actually, I do not have to get used it. If one of our kids has one of our cellphones (which would only be for the purpose of being in contact with us), and they didn't respond when called, or call when expected, they'd be grounded. Period, end of discussion.
