ABG Moment

So I walk into the T and unsuspectingly sit down next to a 20-something a capella group... I should've known something was up - who hangs out with 12 friends on a Tuesday? They started singing theme songs from syndicated oldies (Full House, Wonder Years, Step by Step). Then I recognized one of them as one of those people I kinda know, but have never talked to. Yeeeah, awkward. Although not as awkward as the drunk man wandering through their group. Sigh, seriously, where is the train??
