When my unmarried cousin got pregnant

We lived a door away from our cousins-three girls and one boy. Their parents were very strict. The older cousin was in high school and got pregnant. I remember the morning I looked out the window and saw her standing at the edge of her driveway with a suitcase. Her parents had thrown her out, disowned and disinherited her. Her parents never accepted her or took her back. But the high school did. Three years later, her younger sister snuck out of the house and did the same thing.
