1) Picture yourself in your PJs, no make up, unshowered. Now try to picture yourself in each house. If you can't picture yourself in the house like that, then you may want to cut it.
2) Picture yourself in the letters of each house. As you dou this. Ask yourself are you being yourself in those letters? Are the members you met girls that you'd want to hang with even if they were not in your sorority? If your answer is no, consider cutting.
Follow your heart. And if in doubt, go with your gut.
