Trigonometrically challenged.

The Garden Fairy is a dear soul, she has an awful problem though. Her whole life experience is skewiff, squeuewiff, sqwiff, slanted! 

I know when she has dusted, passed by or touched a picture or mirror, it's always 2º out of true. To prove a point I recently used the spirit level in my iPhone to show her. Unfortunately the problem is so severe she refuses to acknowledge this angular challenged behaviour. 

Perhaps I should just go with the flow but my adherence to the horizontal is not just based on my sleep position, this is an irritant. Knowing this a very good friend always misaligns our tableware and placemats just to annoy me. 

Is there a specialist form of help out there? Not for me you understand!!!!!!
