I'm making my daughter fast until 5pm

Hi everyone! So my 10yr old daughter is usually very kind and loves helping other kids out when she can, she will go as far as to skip recess if it means helping a fellow classmate finish homework. Last night during dinner, she was cackling, just laughing and laughing remembering something that happened at school. When I asked her to tell me my heart sank. She told me her friend 'N' was making of her other friend 'H'. Friend 'H' is muslim and currently fasting, friend 'N' was eating chips and a chocolate bar infront of her while laughing and making fun, while my daughter was laughing and laughing. I immediately stopped her and asked if they were saying anything mean, she said no. I asked her if friend "H" was laughing, she said no.My next course of action was to tell her that even though she wasnt directly making fun, she didnt do anything to stop friend "N' and she kept laughing. So, I told her she was going to fast the next day (today) so that she can see how hard it is and that next time she should do something to stop these micro-aressions, especially if its a friend involved.I am by no means an authoritative mom, we make fun and act silly all the time, but I do believe there is a line and there are certain things that shouldnt be done. I didnt yell at her, I explained as much as I could I am keeping my word though and dont want to say "forget it"Am I being too drastic? Will this traumatize her? I'm worried I didnt handle this like I should have. via /r/Parenting http://bit.ly/2WC4q5D
