Passive Observer????

My daughter is looking at colleges now. She's brilliant and will get in anywhere. We're going to visit a college together. She's scheduled to stay with a student and then attend some classes and go on a campus tour. I was telling a friend how I had the day to myself and my daughter said, "Wait, aren't you coming to class with me and going on the campus tour with me???" "Well, I don't want to go there, what do I care what the campus looks like?" "But, Mom, I want you to see, I want to know what you think." Now I'm thinking, my brilliant, independent girl wants my opinion (this is a first) and I don't want to give it to her (this is definitely a first!). I reasoned that my opinion may actually influence her decision and I want only God to influence her decision. So my husband says that I should go with her and be a passive observer. Okay, first, I'm a mom, second, I'm a woman and third, I'm a mom! In mother language the words passive and observer do not co-exist (wait, what does passive mean??). If I have an opinion, you're going to hear it. Sorry, but that's why my daughter started me this blog, because she was tired of hearing my opinion. I don't know how to be a passive observer. So don't you agree that it's better that I don't have an opinion? I'm so confused. . .just when you think you have your kids figured out, they want to know what you think, and just when you think you know what you think, you don't. . .
