The song "Paper Aeroplane" by Angus & Julia Stone explores the themes of longing, missed connections, and the unpredictable journey of love. The lyrics depict the narrator's desire to reach someone they care about, symbolized by the act of writing their name on a sheet of paper and folding it into a paper aeroplane.

The first verse describes the failed attempt to send the paper aeroplane to its intended recipient. The reference to spilling ink across the page suggests the narrator's eagerness and frustration in trying to convey their feelings. However, the aeroplane stays within the confines of the room, unable to travel the distance to the person it is meant for. It awaits the hands of the garbage man, emphasizing the potential for their message of love to be discarded or overlooked.

The chorus, with the repetition of the syllables "mmm mmm mmm," suggests a sense of longing or an inability to fully express their emotions. It may also imply a certain lack of clarity or uncertainty in the narrator's feelings.

The second verse introduces a new character, the garbage man, who discovers the paper aeroplane and reads the message to his friends. This moment represents the unpredictable nature of fate and how a heartfelt letter can evoke various reactions from different people. Within the crowd, someone's heart will break, possibly realizing that the message wasn't meant for them, while another person's heart may mend as they feel a connection to the words within the letter. This verse highlights the unexpected paths that love and emotions can take, and how they can impact different individuals in different ways.

The bridge describes the garbage man walking home tired from work, and just as he reaches out to catch the sky, the letter falls from his hand, further emphasizing the transient nature of love. The sky symbolizes the impossibility of capturing or possessing love, as it is intangible and constantly changing. The letter is lost, emphasizing the fleetingness and evasiveness of the narrator's attempts to reach the intended recipient.

In the final verse, the narrator spills ink across the land in a renewed effort to connect with the person they desire. The repetition of trying to spell their name suggests persistence and determination. Even though the paper aeroplane hasn't flown the seven seas to reach its destination, it is on its way, passing through the hands of different individuals, until it eventually finds its way to the intended recipient. The song ends with the anticipation and hope that the paper aeroplane will finally succeed in reaching "you," signifying the desired reunion or connection between the narrator and the person they long for.

Overall, "Paper Aeroplane" conveys a sense of longing, missed opportunities, and the unpredictable nature of love's journey. It explores themes of unrequited love, the vulnerability of expressing emotions, and the possibility of finding connection amidst the chaos and unpredictability of life.
