There's a sort of poetic balance between the two halves (since "love" and "lazy" start with the same letter), and to some degree, this superficial resemblance draws attention to the contrast, too.
In finding the specific pitches for the above, I also discovered that "home" in the following line ("So won't you please come home") is sung to a G, which is the tonic note (the song is in G major), so there's a musical sense of "com[ing] home," especially since it coincides with the tonic chord.
