How do you know that once you get to Michigan you won’t be unhappy that it is too big, too far from a major city (and Detroit is not Washington, that’s for sure), too sports-oriented, too Greek-oriented, etc.? Right now you are comparing the idea of Michigan with the reality of Georgetown.
That’s very interesting that you say that, because Georgetown says “Because of the University’s commitment to inclusiveness, membership in a student organization must be nondiscriminatory and open to the entire Georgetown University undergraduate student community.”. They go on to list exceptions (a string quartet could reasonably be limited to 4) but they are few in number.
Can you give three or four examples?
