Worlds Colliding

A week ago, I was at a high school friend's night-before-wedding cocktail hour(s) at a rooftop bar in Austin. He looked at the crowd and noted, "My worlds are colliding....and it's working out okay" or something like that. My worlds frequently collide in DC, and it's tended to work out. So, this week, when a DC-based friend said that she wanted to get people together for a happy hour, I convinced her to have it at an overpriced rooftop martini bar, invited a slew of other people in addition to the 6 she'd invited, and called it an Omnibus Happy Hour....because where else but in DC can you modify the words "happy hour" with "omnibus"?
