Teaching a human to eat mice

I have a sense of responsibility towards my humans. I am trying to train them out of human dsfunction into feline competance, so I brought in a mouse for them. It was pretty good hearted of me, as it wasn't one of the small long nosed voles that I usually spare for them. Frankly these don't taste good to cat so I tend to give them to my humans, who are much less fussy about what they put in their mouths. It's never worked. Even humans dislike voles. I stay optimistic though.
Today it was a real mouse - large and deliciously fat. My mouth was watering, even as I clambered in through the cat flap and set off to find Celia at her wordprocessor. There was a moment of temptation on the stairs. Would I succumb to a little nibble? Sternly I told myself that I must stay with the original generous impulse. I sprang on to her desk and placed the mouse neatly between her and the keyboard, not far from the hard device that humans call a mouse.
At first her reaction seemed appropriate. She too sprang up from her chair with what seemed like a delighted shriek. Then, as a series of completely inappropriate vocalisations followed, I realised that an emotional sympton of musmalfunction ( a disordered reation to mice) had taken over. She threw herself out of the office then came back with yards of lavatory paper - just too late. Realising what had happened, I had smartly picked up the mouse and was legging it down the stairs to the cat flap and out on the lawn for my delayed meal.
My generosity ignored and insulted. Not a word of thanks.
