"My Girl" says affection can replace the conditions around the speaker. Bad weather, cold, sweetness, song, money, fortune, and fame all become secondary because one beloved person has changed the scale of value. The title phrase works because it is both private and public: David Ruffin's lead voice keeps the address personal, while the backing responses make the feeling shareable.

That is why the song's simplicity holds. It does not argue that love is complicated. It argues that one clear attachment can make the world feel reorganized. The repeated title keeps that claim plain, generous, and public enough for the whole room to answer with him.
