Rich, maybe it's best your wife just sticks to the reality she knows best. smile

Every time I'm out
I'm full of doubt
In the world of the material bazaar
Outside I feel
Is not really real
Am I sensing things as they really are?

Inside I find
A trustworthy mind
Freed from illusions blurred
The thoughts that appear
Are so crystal clear
Mind over matter preferred

That leaf that I glean
Is not even green
Nor it's shape so simple, distinct
It's a fact that the green
Is but a smokescreen
And the shape is wavy fields linked

But inside my beef
A leaf is a leaf
No blurry senses buffet
There is no deception
Upon leaf's conception
No mind games whatsoever at play
