Love is a ship, it will break and can drown you. It can be repaired, but the nails and boards will always show through. It takes time to fix, slowly mending but never quite the same. Love is constantly changing, The gentle stagnation of the repairs, The gentle stagnation of two hearts as they understand one another. Love is a ship, It will break and can drown you, but is can alter itself to the perspective of the world it dwells in.
A metaphor like Love is a ship is a conceit because I'm comparing two things that are thought of as incomparable. That is the purpose for the title.
