Empty phrases - "How Are You"?

The art of conversation seems to be becoming very formulaic. I am really fed up with listening to radio 4 programmes where interviewees monotonously say "thank you for having me" & "how are you"? to the interviewer. Neither party is there for a friendly conversation. They are there because something is newsworthy enough to be on radio 4 & there are questions that need to be answered. Hopefully both parties are well informed & have something worthwhile to say.

If you say "how are you" to someone I feel you should actually be interested in the answer & be prepared to give it the attention it deserves. It shouldn't simply be a glib, not expecting a proper answer, conversational gambit. We all play the game. We all respond, "I'm fine how are you"? & don't expect any real information. It's like Brits conversations about the weather, utterly pointless.

Similarly "thank you for having me". What on earth does that actually mean? How can you "have" a person? Both parties are in the interview in order to convey information. The phrase is transactional, facile, superficial. They need eachother & are there for a specific purpose. Generally the BBC does not pay members of the public for interviews. There can be exceptions for experts, consultants, or those involved in high-profile news stories, but the standard practice is not to compensate individuals for participating in news interviews.  

Conversation should, of course, be polite. There is nothing worse than interviewer & interviewees speaking, or even shouting, over eachother, although it does happen more often than it should. It defeats the object of the listener being informed & getting information & is extremely irritating. Personally it makes me turn the radio off. 

The most empty phrase of all time has got to be "like". It's a filler word like um & er, it's how we make time to formulate a thought or word. Goodness knows how it has become so prevalent. People don't seem to be able to tolerate silence any more. Silence allows us to think. But I feel we have lost the art of thinking before we speak or act. Some people just want to be the one speaking, even when they actually don't have much to say.
