Let me tell you a story of long, long ago.
I grew up in a suburb, and right in front of our house was a field of grass surrounded by houses. Traffic was light, the houses were new so owned by young families (yes, it was so long ago that young families could afford a house) and so there were lots of kids always about outside. Across from us lived a boy my age who was also in my class, and I played with him a lot -- we were good friends. Eating lunch at each others' houses, etc. 1/
