My prof is going over last week's homework, even the questions everyone got correct. Since, at the post-half-marathon brunch, several people knew each other through a couple degrees of separation (including our server to two guests!), I'll try to explain some of these relations to the tune of the 12 days of Christmas.
12 twenty-somethings
11 omnivores
10 college graduates
9 MIT affiliates
8 engineers
7 young women
6 Second Easters
5 'puter programmers
4 members of the tribe
3 bio majors
2 engaged couples
...and one person whose coworker was the server's roommate
Okay, that wasn't as funny as I thought it might be, but at least it kept me entertained.
