School bells are ringing once again, and come September, many a student or intern will flock to D.C. and choose to nest with a number of other similarly situated kids. And, pardon the use of a second animal kingdom metaphor, they’ll cram themselves, willingly or forcefully, like sardines into one of many converted group houses surrounding the city center. Group house living is a feat in patience and Flickr user nikoo yahyazadeh has documented one sunnier aspect of co-habitation. After all, we are social animals by nature, but maybe the bathroom is one space not meant to be so liberally shared.
