Communication is something extremely essential in our lives and without it, we are able to do things properly and if that happens, our lives will be havoc and messed up.
My favourite forms of communication are through e-mails, smses and chat on any world-accessibility platforms because they are easily accessed through nowadays' technology. Technology is so good that we can communicate through anything, which is good for us, as "high-tech" people.
It really depends, if you're at different parts of the world, e-mail or chat is better communication. If you're nearby your kins, but you're lost at somewhere, a call or sms would be essential and recommended for me.
In my opinion, you wouldn't know if its true where the person you're talking to is located at where. And at times even if you tell them something or directions to get to somewhere, they might not understand you, which is one BIG con I dislike about communicating with others.
