change her mind

Last week my friend called and invited me for the Christening of her grand daughter today. I told her that I am not sure I could go because there is nobody who can watch my babies. This afternoon another friend called me and said that she would pick me up and my children to go to the Christening. I was in a hurry to get ready because she said she would be here before 5pm unfortunately she never showed up and she never even called me. I was very upset and my son asked me why she was not here? I said maybe she change her mind. I could not call her because she never gave me her new cell phone number.
