One of the hardest things about living in Ithaca is having to constantly say good-bye to friends. Students come for 4 years to get their bachelors, or perhaps 5 or more for a PhD. A few of them stay, but most are in town briefly before they are on to the next thing.
We knew one person who worked at Cornell who had a rule that he would not make friends with associate professors until they received tenure as it was too hard to keep saying good-bye.
