One thing I won't be able to provide to my kids easily is the huge community of +-same age kids nearby them. I grew up in one of those communism-planned tall concrete buildings, and within our building (I think 4 different entrances) there was maybe 50 kids of my age, +-2 years. There were another 20 buildings like that within 1km. Due to time of raising the building, most families had 1-3 kids of same age.

Many went to same school as me (200m far, walked there alone from 2nd day) so we kind of knew everybody. All the crazy games, adventures... my parents just sent me out, I came back in 3-5 hours, and they had no idea or control over what I did. I went to distant forests, metal scrapyards, climbed on roofs of buildings that had ladders (including our school), played tons of made up games. I considered this a normal childhood, nothing special.

Now I don't think it would be possible anymore, too much changed. In system, people, mindset.
