Ooh I LOVE KUA and do a good Hyacinth impression- Rich-erd! It's definitely a show that keeps on giving, we still quote it (royal doulton, or a pink burglar alarm anyone?) and remember the episodes fondly here. I can see why it was a hit round the world, too. Hyacinth as type is universal.
I think Richard is happy with Hyacinth really, he loves her. Well, he humours her, doesn't he? He just has a much needed ally for his sanity in Elizabeth! It is- as a Pp has said, Daisy I feel most sorry for. She should have LTB. As should Violet- married to Bruce the turf accountant but suspect she'd never leave her two-mercedes-room-for-a-pony lifestyle, no matter how often Bruce wanted to wear her Maid Marian outfit instead of letting her wear it.
As a child, despite giggling at her ways, I used to wonder why people were so mean about Hyacinth when she had a nice, clean, pretty house, as I saw it! I'd still rather live with her or next to her than with or next to Onslow & Daisy! She also always sorts out the family mess- they turn to her with all their dramas. She was the only one of them to handle Daddy!
Oh- and Shirley Stelfox was the original Rose, yes!
