Three short stanzas, and one small twist that changes everything. The speaker starts by saying they are running from someone, which sounds like fear or escape. The second stanza, "out of the blue," makes it feel sudden, as if the urge to flee came without warning or a clear reason. We expect a story of leaving.
Then the last stanza turns it around. The speaker is running "home / To you." The same person they were fleeing is also the place they want to be. That pairing suggests a tangled feeling: maybe the closeness is overwhelming, maybe there was a quarrel or a moment of panic, but the pull back is stronger than the urge to get away.
The repeated "I'm running" gives the poem a breathless, restless rhythm, and the short lines read almost like quick steps. The mood moves from tension and uncertainty to relief and warmth. By the end, running feels less like escape and more like coming back.
