For me it is a song about a re-encounter of former lovers. He has flown from his hometown to meet her (and that's why she mentions "the miles he made") and, since they are nervous they both deal with anxiety with different methods: weed, wine and even a speech for the moment. They spend a night and maybe more together doing what they used to (listening to DFA, of course) but eventually he has to go back and he does so all alone. She keeps a mixtape he made to her and, when she listens to it, she feels connected to him.
