Is this how it will be?

So Hannah has been gone since Saturday (officially without me) and I have talked to her twice. Two times in almost a week. NOT ACCEPTABLE! I was expecting a nightly check-in call telling me how class was, that her homework was done, that she is taking a shower and brushing her teeth nightly. Not only am I not getting that but she was in a terrible hurry to get off the phone! SHE told ME she had things to do! What things? More to the point, what things that are more important than talking to her mother? Is this the beginning of the end? Is this how it's going to be when she leaves for real college?
