A woman is reminiscing about her ex boyfriend and how much she misses him. She places a call towards him in hopes of talking and meeting up again. She uses the metaphor 'us and a million miles' to represent how far they've drifted apart and what she wishes to happen between them. She acknowledges her mistakes by saying that its typical of her to talk about herself. This is mostly just a song about how Adele misses a boy and wants things between them to change. By saying hello to a new beginning.
