I can honestly say that I've had a sister who didn't drink at parties. I've also had sisters who have remained virgins until they were married I know sometimes girls worry about that too(just in case this was an issue you were afraid to bring up)... we had a girl rush the other semester and that was a big issue for her... her blood sister belonged to another organization but she didnt want to belong to that one because that wasnt who she was. If you find the right group of girls they will accept you for who you are. If you are ever put in a position where you feel like you have to compromise your morals or values to be accepted runaway thats not the place for you... your sisters will love you for who you are ... or in this case who you are not. You should go somewhere where you don't have to be anything but yourself.
Depending on your situation you might even be surprised to find that some fraternity boys will respect you on a higher level as well
