Everybody is someone's something sometime.  At any given moment there are different people occupying the Bane of My Existence, Most Favoritest Person Ever, Source of Concern, Miss Horribly, Needs XYZ From Me and I Need to Make Sure I'm Giving It, etc. Hollywood Squares-style boxes in my life; it's both encouraging and sobering to remember that I am continually occupying various of those boxes for other people.
