As a little girl in the 70s, I would have just finished a very traditional Sunday dinner with all the trimmings (which I hated) even though my Mum was a good cook. Loved Vienetta for pudding though. After, Dad would wash up with military precision, and my older brothers and I would dry and put away the dishes. My brothers would bicker about who was drying more 
Then, it would be bath time - but, unusually for the 70s we all bathed every night anyway, using fresh water each time. My Mum was fanatical about personal hygiene and cleanliness (thank God). I would have Miss Matey for bubble bath and use Imperial Leather soap. Clean polyester nightie from BHS with a collar and ribbon bow at the neck, had same one in pink, lemon and sky blue.
We'd then all get comfy on our large, forest green, pleather sofa (with matching swivel chair) and watch something like That's Life, or The Two Ronnies. Or, we'd listen while Mum played her Roy Orbison or Nolan Sisters albums, on the huge, teak gramaphone in the living room and I would dance about. My brothers would be bickering about something or nothing.
In the Winter we'd have Horlicks at bedtime and bizarrely I used to like to go to bed early so I could read; always Famous Five or Secret Seven.
