.. and not to do what my BIL does every single time. Conversation goes like this:
Phone rings, I answer:
Me: "Hello"
BIL: "Hello"
Me: "Hello?"
Long awkward pause
BIL: "Hello"
And so on, and on and on. Drives me mad. I have no problem asking what he wants, but that's not the point. All very trivial in the grand scheme of things I know, but he's been my BIL for about twenty years now, and he still doesn't know how to converse properly.
