When I was looking on Lowfield, I came across this reminder of what Peggy can be like:
Helen seems more relaxed in the company of her mother and grandmother, though has a momentary panic when Henry disappears to look at a piglet. Luckily Johnny is on hand to help Henry summon up the courage to touch it. Peggy is in full-blown disapproving dowager mode; Henry is too old for a soft toy; Lynda and her pageant are quite beyond the pale; fancy Henry being scared of a piglet. Pat changes the subject rapidly.
Peggy waxes lyrical about the wonder that is Rob. Helen must be so proud of him. Unfortunately Helen thinks she means Henry. Helen fetches cake for Peggy, but is 'too full' to have any herself. Peggy expresses concern over Helen's appearance - characteristically Helen flares up. Pat tries to calm the situation, and as she drives Peggy home, is treated to Peggy's opinion: in her day women did not have hormones. They just rolled up their sleeves and got on with it.
Let's hope current events are opening her eyes.
