Another Word You Know

Like a word that you didn't know, but once you do it follows you everywhere, this one stalks me.

Reginald Shepherd. David Foster Wallace. The 22 (and perhaps more) in Delhi. The poet's daughter who jumped from the eighth floor. I see it everywhere, even - like the man in the ad - when it is only one half of another word: knell, throes, mega, little, sudden.
