Yes, indeed. We may not be able to keep track of how much we've changed and we may not notice the changes that happens to us mainly because they're just small changes, but still what's clear and sure is that you've changed, we've changed and is still changing. We were changed/ transformed and is still being transformed into a new person by the devices that we use because as they have said, it has already become a part of us, of who we are.
      It's alarming and somewhat frustrating because we can't seem to leave this devices for just a short period of time. We always look for it. Whatever we do and wherever we go, it's always with us. Every minute and every hour we can't seem to have it off our mind. We loose our patience and we become easily irritated and all of this is the result of relying too much on those devices.

Well, you still can control what you're going to say in a conversation not unless, you let you're emotions rule you. If you want a controlled answer to the statement or question of your conversing partner, then you should open your ear to listen, your eyes to observe, and mind to analyze and think. Be attentive. If you want a controlled answer, take your time to digest what was said. Take your time to search your brain for the best word that you think is the proper and exact one that you should use for your response. Just see to it that you don't take too much time thinking.

But well, that's how conversation is. That's it's nature, not in all conversation what you need to say is controlled or filtered.

It does. The only problem is that you won't know them hundred percent but you'll somehow have an idea on how and what they're like. Actually, just by the message itself, the structure, the style or the way it has been typed, you can already guess some of their characteristics/have an idea on what that person is like.
