"Time is the most extraordinary gift for friendship. You'll get to eat your meals together and study together; in some cases you'll even sleep in the same room. You'll have time to waste on each other. You'll find out every single thing you have in common and still have time to catalogue all of your differences. Don't underestimate the vital necessity of friendship in your life because it is the thing that will sustain you later, when there will be considerably less time."
