talk / chat / conversations

[san]

hi!

what is the difference between talk / chat and conversations.

what about the sentence " lets keep our conversations going." ( not government people talking)

thanks

1. We're having a talk. <could be serious>
2. We're having a chat. <not serious>
3. We're having a converstaion. <exactly that; we are talking>

4. Lets keep our conversations going.
=> I've heard this used in business, and I have seen it used on MSN chat.
