Professional party pooper (and Houston head honcho) Annise Parker exercised her authority on the evening of July 4, halting a house party in her Montrose neighborhood.

Following the incident Monday night, the spoilsport tweeted, "I just personally (& rudely) shut down a loud neighborhood party- 11:45 pm! Were they surprised to see me. Security will not be happy. -a"

Perhaps the mayor was all tuckered out after attending a Kingwood parade earlier that day — a drama-riddled event, according to her penultimate tweet, "My mounted patrol horse bolted! I finally got her stopped but it gave my security a turn!-a."

Is Parker a walking wet blanket, or just a professional trying to get her beauty sleep before balancing budgets? Perhaps she was sore from mounting that horse? Maybe the Rice University alumna cannot fathom the idea of partying on a school night. Or worse: Does our mayor hate the Fourth of July?

CultureMap asked the party sourpuss for comment, but the mayor's director of communications Janice Evans came back with, "We're going to let the tweet speak for itself."
