She has a two year old daughter. She is just assuming she can leave her with her mother. Abdicating her responsibility. She is definitely behaving like teenager. So many youngsters behave like this. They do what they want and to hell with anything that gets in their way.
She doesn't leave her daughter with her mother - on the nights she stays out, the child is with the father.
And at nearly 30 years of age, she's hardly a youngster!
The issue is - to my mind anyway - one of simple courtesy. If you live in your own home you can come and go as you please, but if you are in someone else's home, it's just common courtesy to - within reasonable limits - let that person know if you plan to be away for any length of time. For practical reasons as much as anything else.
