I agree with all of them except the second excuse to use when wanting to cut a conversation short, you shouldn't say you'll be back if you won't.
I also advise not to monopolize the conversation. Listen more than you speak. Ask questions about the other person's business or line of work.
What are your thoughts?
Please post them on my blog.
