Meaning of "156" by Mew

The lyrics of "156" by Mew seem to convey a sense of longing and unrequited love. The narrator watches Callie from afar, wishing to be close to her but recognizing the distance between them. The repeated mention of "if you've got the money for me" suggests a transactional aspect to their potential relationship, hinting at themes of materialism or superficial connections. The mention of goodbyes and inevitability could symbolize the narrator's acceptance of the situation, understanding that they may never truly be together. The references to being covered up and small contrasted with big goodbyes hint at the complex emotions involved in letting go, even when one knows it's the right thing to do.
