In India, there was a neighbours kid who practically grew up in our house. He had dinner at our place...we had cable TV (first in our street )..he would be watching TV and some days he would just fall asleep and we would tuck a pillow and cover him with a blanket.
The first day I was in the USA (Texas), I was advised by my cousin who received me to not to wander around into neighbors property or knock on the door. He said I have to take appointment before visiting them else I could get shot for trespassing.
