answer:I wouldn’t say anything. I understand your concern, but most likely she very much enjoys time with you. When the right opportunity comes up you can reassure her that she shouldn’t feel obligated to spend time with you and miss out on something she would prefer to do, but also she should know how much you enjoy being with her. Maybe you can talk to her about your own experiences when you followed what you wanted to do, or not listening to yourself when you didn’t want to do something, and some of your regrets about it. Then it’s not a lecture, but more a sharing of life experience. Another idea is when she needs to cancel be sure to let her know it’s no problem at all and be excited and interested in what she is doing instead. I think this sort of thing is so tricky. Teenagers especially assume incorrectly what adults are thinking. Even as adults, in adult relationships, assumptions of this kind and miscommunication are the source of discord and discontent.
