Life, Universe and everything

I've got a question. 

How come food from YOUR plate tastes ever so much better than the same food off my plate?

Aunty Wendy came up for tea, and I made such a fuss about being in the family room, they did let me come into the front room so long as I didn't run around.  As if!!

All I wanted to do was sit on the settee and gaze longingly on plates for a crumb - any crumb - to come my way.  And it wasn't even roasted lamb.

SHE did make chicken schnitzel, and it smelt so good - and I didn't get any of it.  All I got was plain chicken on my own saucer.

Didn't even come close.
