It tells a story of a family trying to escape slavery. The family consisted of a dad, mom, and their teenage son. The family had experienced all the horrible things slaves experience. In addition to the abuse, the owners were planning to sell the son off. Not wanting their son to be sold, they resorted to desperate measures; they encouraged their son to runaway.
Can you comprehend the danger that comes with a slave running away? How hard of a decision, to be in a place so dire that running away from slave catchers is a better option.
So the parents instructed their son on how to get away and told him they would also run away and meet him. The meetup place was confirmed, which was a free state in the north.
Once the son had left, the parents also ran away. The son took a safer route, if there is such a thing. The parents took the route of the woods; underground.
The parents made it to the meetup place before the son. They were trying to adjust; trying to make a life for themselves as they waited for their son.
When the parents first arrived in this free northern state, a gentleman who met them sent them off to go in and change from their wet clothes.
There was a moment when the dad just stopped what he was doing and began to laugh. It was a deep, joyful laugh. The wife heard him and asked what was wrong. She wondered what was so funny. His response to her was, "We're free."
He went on to say, "We can laugh out loud, as loud as we want! We don't have to be quiet when we talk. We can do what we want! We're free!" And then they laughed together.
