Sammy Daisy,
I would say go for it! You'll never know unless you try and it would be awful if you kept thinking to yourself "what if" There's no way to tell what has happened in the past with you not joining a house. Sometimes weird things happen in rush and its just one of life's great mysteries! Believe me, you're not the only one! I don't know when your school rushes but if its not too late i would sign up. You can go to the parties and make up your mind and you don't have to accept a bid if you don't want to! Good luck with your decision!
