The tail... what does it mean/ Can humans read it?

Dear George, 

I need your help in finding a common language with my human.

She is pretty smart and she did learn fast cat language but, for whatever reason she is quite stubborn when comes to “tail language”.  She doesn’t understand that we are way more sophisticated than dogs and we also “communicate” with our eyes, face, tail, body, etc. She takes the simplistic approach just like a dog!

At times she makes me think I’m training a dog not a human! I’m sure you’ll agree with me that cat tail wagging can mean so many different things! For example: when she calls me, unlike a dog who would be happy to come when called, I like to take my time and analyze “the call” – is it worth my time getting up? Is it about food? Or she just wants company? But, she doesn’t understand that because she doesn’t speak cat tail language!

So, she comes running throughout the house looking for me everywhere and disturbing my quietude! 

George, can you help?

Dear Katho,
Humans don't understand tails at all. Why should they? They don't even have one, poor mutilated things. So reading a tail, by which we can express so much, is beyond most of them.
Tail language, of course, is obvious to us. There is TAIL UP, a sign that we like the person we are approaching. We're flagging it up, as we walk towards them, as a sign of greeting and liking. 
Then there is BUSHY TAIL. That's just the opposite. Our hair is literally standing up with rage.  At about the same time, our tails are usually going up, then sort of drooping down to cover our backside if we get in a fight.
There's LASHING TAIL.  This is clear too. It says, "I do not like this. Stop it. Or I may bite you." LASHING TAIL is also part of our hunting procedure. We stop, eye the mouse, stalk and then lash the tail as a kind of balancing movement before the pounce.
What else? Well there is just TAIL MIDMAST.  That's the relaxed tail just hanging out more or less in line with our bodies, when we are just relaxed about about life in general.
But how are you going to get this across to her? Most humans can't red their at all. Write to me again if you have found a way.

Yours 

George.
