I destroyed an underwater camera

So hello everyone, I just made a mistake at the pool party that was yesterday.
It was kind of just a miscommunication on her part, so that is why I messed up and made the mistake because I was thinking something else.
And I was supposed to be paying them for the camera but instead I just gave them this one I got for free I never ever use and that made them happy they liked it even better! Also then I took theyre mouse(For the computer) to make the value equal.
