"Don't Bother Me"

I listened to With the Beatles yester-day and noticed a small feature in "Don't Bother Me" that I think I've commented about before with other songs.  In the line "It's just not right when ev'ry night I'm all alone," the phrase "all alone" alliterates, and since the two words start with the same sound, there's a sense of the singularity of being alone.
