Written by Pretenders lead singer Chrissy Hynde, this song describes the complexities of love from a female perspective - she's inconsistent, but wonderful, and wants her lover to know that he shouldn't get too worked up, because she could change quickly. Hynde put a lot of weather references in the lyrics, implying that her mood reacts in a similar fashion.
This was the last big US hit for The Pretenders. This frustrated Hynde, who remedied the situation by asking the top songwriters Billy Steinberg and Tom Kelly to write some songs for her. This did the trick, resulting in "I'll Stand By You."
