Sociological impact on BYU-Idaho Dating

My apologies, I am getting all of the angst and disgust filled posts out of the way before I move on to more important other subjects. My roommates and I are planning a day trip to Jackson Hole Wyoming and one of my roommates suggested that we all invite someone to come with us. So I asked someone if they wanted to go and she said it sounded like a lot of fun, but that she was going out of town this weekend. That of course is all fine and dandy. She can do whatever she feels like doing. Today as I was walking home from my class I was her walking holding some guys hand. Now let me make this very clear- the fact that she has a boyfriend is not a problem either. That's great. But saying, "Oh I'm sorry, I'd really like to but I'm going to be out of town." makes it sound like I have a chance to ask her out later. If she has a boyfriend obviously I can't, so just say that you are taken and move on. I won't die i promise!
But of course after she said she was; "leaving town" I asked a few other people, not in person and of course not at the same time, and they have completely ignored me. I have a new word for you. It is a short English word that is used when you don't want to do something: NO. Two letters. One syllable. But girls at BYU-Idaho seem to be afraid to use this simplest of English words so they don't offend anyone. I realize that this is not entirely their fault. The socialization of Mormon girls requires that if they are asked on a date they should say yes unless they are in fear of their lives or chastity. Good moral idea. But if they just plain don't want to go for their own reasons they feel that they have to make up an excuse or not respond otherwise they may make it sound like they are afraid I'd jack them up or something. I'm not going to so they have to get creative on excuses. I think the socialization of BYU-Idaho females has messed them up in terms of complete honesty. I don't think this is entirely their fault, and am willing to give them the benefit of the doubt, but really if I ask you out and you don't want to go just say no and we can still be friends instead of ignoring me and then I always wonder when you're going to do it again.
