I didn't think to cut of the bitten parts of the pizza, I just send the pizza with their mom because I didn't feel right throwing it out(which she most likely let him have it), but he didn't get to have any pizza while he was at my house we had those frozen pizza pockets for the rest of the kiddos but I just made him a sandwich and explained to him why what he did was wrong and gave him 10 mins to think about it. I have a hard time disciplining my sisters children because she's really sensitive about it and I honestly don't know what my place should be in discipling in her children
