Here are six pet-hates my Italian-born mum nurtured about the UK after she married an English soldier and moved there in the late 1940’s in
- The death penalty. (Finally abolished 1998, though last execution took place in 1964).
- Sundays. (Trading laws finally eased in 1994 but still limited for larger shops).
- Gaberdine raincoats especially if forming part of school uniform.
- Hypocrisy (make your own examples for this).
- Long time involved in much building works when compared with post-war reconstruction in Italy.
- Loathing for some historical figures especially Henry VIII ( dissolution of the monasteries) and Cromwell.
My mum’s pet-loves regarding the UK would include- Much less ‘mammismo’ with kids (being tied to mum’s apron strings) than in Italy where kids aged thirty could still be living with their parents.
- Odd millinery for women and evocative hats (esp bowlers and boaters) for men.
- ‘High tea’ (with cream cakes).
- The northernmost part of the Kingdom (especially Scotland and Orkney).
- Gothic cathedrals (especially Salisbury – although she loathed Westminster abbey as it was spoilt by all those monuments in it).
- Her English husband (especially his practical know-how and do-it-yourself).

So there you are: six of one and half-a-dozen of the other.
I like your mum’s list.
