– Give yourself a pat on the back as you return to D.C. for possibly contributing to the city’s latest superlative: ninth drunkest city in the nation.

– With Inauguration Day looming, get back into a political frame of mind. Supreme Court Justice Sonia Sotomayor will speak at Lisner Auditorium Friday as part of Politics and Prose bookstore’s speaker series. Tickets for the 7 p.m. event secure you both a seat in the audience and a copy of her memoir, “My Beloved World.”
