Hi CMG,
Welcome to PC.

I would advise you to just go slow and don't over think what you want to say. sometimes we try to say everything at once and end up not making sense to people or we sound silly. Let the conversation flow easily and natural. Preparation for a conversation rarely works because of the nature of a conversation. what you are doing is rehearsing a speech. Forget about a speech, when engaging a conversation both side get a chance to talk and you can rarely anticipate a response unless you are in a debate.

Hope this helps you,
