Oh this thread is so evocative!
I remember my grandparents house as being absolutely HUGE (of course I was very small) with fantastic views - it was in the Lake District.
Going for walks - Aira Force and Tarn Hows were two of the favourites, and boat trips on Derwentwater.
Walking on frozen lakes in the winter.
Grandma was a fabulous cook, she made the best Sunday lunch ever - the memory still makes my mouth water, even though I don't eat meat now. Amazing Yorkshire pudding which Grandpa had as a starter with gravy.
Cucumber and onion salad with vinegar.
Homemade bilberry pie and cream, "Everything in moderation" she would say as she LADLED the cream over.
Trifle.
Snowballs to drink on Xmas Day (yes - for the kids!)
Tins of Quality Street.
"Coffee buns" with coffee.
Making lemon curd.
Making toffee and then breaking it into pieces with a toffee hammer. Sometimes it turned out as fudge.
The sound of the Grandfather clock ticking and chiming. It stood in the hall, next to the Lang settle - a sort of wooden seat, a bit like a church pew.
Sitting next to GranGran (Great Grandma) in the kitchen next to the Aga while she told me stories.
Their car - inside was basically two leather sofas. I used to sit in the front next to Grandpa with a rug over my knees. Tin of Mintoes in the glove compartment.
