In my opinion, the best way of communication is by using technology. When we using technology to call it will be more comfortable than when we talk. By using technology to call, sometimes there will be some mistake like calling with no wifi or we can't hear the one we call. All of those problems will be fixing in no time! Today, modern scientists are researching wireless technology so we can call it with no Internet! How comfortable is that! But we still can't hear exactly what is the opposite is trying to say, it does not have any solution yet but I believe it will be fixing as soon as possible.
