You know, I'm a (very recently former) student, and I've lived in Boston my whole life. I never went to school in Boston, but still...I'm pretty convinced that every school within the city limits needs to hold a week-long course on "city etiquette".

Also: 9. Yes, we know you're happy to see each other again, but when congregating on the sidewalk, please keep your screaming, tearful reunions to under five minutes or under fifty decibles. Also, as a courtasy, please don't take up the ENTIRE sidewalk, forcing pedestrians to either burrow through you, or risk their necks to traffic darting around you.
