If you are a sailor on board a ship that makes port, you may decide to go ashore to bring back water. Along the way you may stop to collect shellfish, or pick greens. But you always have to remember the ship and listen for the captain's signal to return. When he calls, you have to drop everything, otherwise you could be bound and thrown on board like the livestock.
So it is in life. If, instead of greens and shellfish, you have taken on a wife and child, so much the better. But when the captain calls, you must be prepared to leave them behind, and not give them another thought. If you are advanced in years, don't wander too far, or you won't make it back in time when the summons reaches you.
