How do you know if a conversation is finished?

Well I do have a smart phone at the insistence of my family. My problem is, I can phone home or answer my phone but nothing else. I have found out from friends that they had sent me a text message giving me times and places to meet them for a coffee. Of course I didn't turn up because I didn't know that I had received a text. Also, I do not have a clue where to look for a text message. If I found a text message on my phone I don't know how to send one back. Why can't people just use their phone as a phone. At least then I could answer them. I very rarely take my mobile phone out with me, and I manage fine without it. So to answer your question I don't do text messages so I don't have that problem. lol...

A good topic! As to me, it depends on whom I have a chat with. Usually, when I chat with my friends, I would tell them that I have to do other things and finish it, sometimes they finish the conversation by telling me directly too. And sometimes, we just don't answer each other, and it's just finished.

Wow. Right on, great topic! I am not sure either and I just assume as the answers get less and less frequent (more and more time between the replies) its fizzling out and sometimes unintentionally when I don't reply, that has been it, so I guess that's the unofficial close to a chat!
