When this mom doesn't know how to she's supposed to react to her daughter, she asks Reddit:
So I (36f) & DH(38m) adopted 2 bio sisters fostering them for many years. My oldest Anna (19f), her BFF London (18f) & I were sitting at our dining room table going over budgets because they want to move out together & wanted to know what they could afford. With the way our house is situated where I was sitting at the table I could see our stairs going upstairs, the living room & the front door.
When Anna, London & I first sat down Madison (16f) burst through the front & stormed up the stairs & proceeded to slam her bedroom door. Par for the course of teenage girl living but I asked Anna & BFF if they knew what that was about.
They both said no. I thought that Madison was supposed to be hanging out with friends that day. I wasn’t even expecting her home til way later. I gifted Anna a budget journal & told her & BFF to start filling in some of the info & I was going to go check on her sister.
