Family of liars and backstabbers

My daughter spent the night at my mom's last night she promised to bring her home today, well my brother took her out of town with his gf and her nieces and nephews they didn't even ask me for permission I was worried not knowing where my child was at. They then called me around 2pm to let me know that they went to the aquarium in long Beach like wtf? You didn't tell me? I was upset all day and I told them that they can't see my kid after this for disrespecting my trust and boundaries, my mom is playing it off telling me to mellow out that my daughter needs to go out and experience life because we live in a small town. These people are fcking stupid I'm tired of them.
