: anybody can help me out what this means...
: me english no so good

It means what it says. She is a metaphorical girl who lived in the next house(= next door) to a boy. This girl has come to symbolise the perfect woman of adult life.
In real life, boys and girls who actually lived next to each other have rarely found perfection in the other!
