My friend, who is older than the Bambers were, have three grandsons who regularly PLEAD to be allowed a sleep over with Grandma and can't be torn away at going home time. I didn't have grandparents but I did have several "greats" with whom I was required to be on my best behaviour. One of them constantly admonished me to "Sit up straight, darling" although I recall that her husband was jolly. I have a feeling that the Bambers, as grandparents may have been closer to my "greats" than to my friend.
My " greats " were like that too,Jane. I was scared witless of the darkness in the sitting room with its chenille curtains, drapes of cream net curtains, a huge aspidistra plant and an enormous g/father clock whose chimes frightened me to death. No wonder no light came in. An over-powering smell of mothballs too. Then the aunts all in black full length frocks,crisp lace edged aprons and mop-caps,towering over this 6/7 year old child-----me !
I couldn't have stayed in that house if you'd paid me,even as a child I'd have kicked off,I know I would.
My only reason for accepting this mob of arsenic and old lace was that I was with my dad ( his relatives ) and that I'd be going home with him----soon

That's why I felt for the twins because I hadn't wanted to be where I was at the time.
