How far is the school from where you work? I'd get her up and take her to work with me if I went to work early, and let her walk to school when it was time or take the bus, if it was safe. If she can't get herself up at a later hour, then she should be up and dressed at least with you. If the school was open early and she had a lobby or someplace safe to wait until it opened, I'd take her there. Soon she would learn she could get more sleep by getting herself to school. Yeah, don't be her friend, and don't assume that she would smoke anyway. Be pretty clear about how you don't smoke in your family. If she is irresponsible and can't be on her own without sneaking out etc., send her to a relative's house when you need to socialize, or get her a babysitter with a cell phone to call you if she does sneak out. You do need some separation. mg
