I miss old fashioned libraries where everyone had to speak quietly and there was no running around. Nowadays my local library is like a crèche and the elderly people who used to go in there to read the paper and keep warm just don't bother.
I also miss old fashioned Sundays with church bells ringing, and roast dinners, and no one playing out because it was family day, and cheese and toast beside the fire before watching the big Sunday drama. 
Just wondering what other OPs remember and regret no longer exist regarding their childhood?
