When my egg doner got custody of me and my 4 siblings at first it was okay; she would treat us great by bringing us to the park, taking us to see our family, letting us see our friends, and even getting us small things every here and there. It gradually became worse over a short period of time; it started with her harshly punishing us for little things, and then it became beatings for us saying something she didn't want to hear.
She once beat me over a can of tuna she had accidentally left in the backseat of the beaten-up car. She always thought I did something wrong. In hindsight I realize I either didn't do anything wrong or what I did was not that bad; she would beat me for things such as not folding the laundry, dishes, or sweeping the floor immediately after I was told even while I was doing another task. I was always walking on eggshells around her watching my every move so that I wouldn't get hurt that day.
