What I think about Pat butchers earrings. (but might be wrong)

it seems to me that she uses the larger earrings as a device for instilling
respect even fear, the larger they are the more terrifying.

They operate like the mane of a lion or the heckles of a dog acting to
intimidate in moments of heightened arousal when she needs to be at her most
'Pat'.
This is demonstrated in the image with the black droppers huge
impressive and we see her (and her scary but sometimes sensitive mate)
coiled like a mighty spring.

The more modest ones (yellow dangly 'cut' amber) seem to be employed when
she is in a more sensitive, reflective or philosophical mood and seem to
reflect a calmer state.

With the diamante danglers we see Pat in a state of brave misery. These were
probably sported for a date or a reunion that went wrong.

The classic pink droppers depict Pat in a defiant mood. Possible scenarios
include a great night out with Roy with some family secret threatening to
reveal itself and Pat saying "don't you dare ruin my special night out you
tart, it's my anniversary"

I agree the Black ones are very classy especially with the cigarette. I
think in this image Pat is preparing almost meditating on Patness what it
means to be Pat and how Pat will be ready for everything that life throughs
at Pat.

Nb: I have never seen her wearing green earrings and I wonder what it would
mean if she did.
