1. You always have someone to hangout with
For those nights that your friends bail, or when you need a good rant they are always there.
2. Your parents only have to write one check
Yeah... it may be twice as much, but who's really counting?
3. It takes some people a long time to figure out that you are related
We've only been on campus together for 2 years, and there are not that many students and our last name is pretty unique.
4. If you are younger, you might already know people by the time you get to campus
5. You have the best support system that you could ask for
6. One of you will call home occasionally
Since one of you calls home, you can take turns keeping each other updated.
