Two Yellow Days In A Row

I was really disappointed when my son told me that he got another yellow day today. I asked him why he got another yellow day at school and he told me the reason why. He told me that he didn't want to stand up while they are practicing for their graduation thing, I was really disappointed and told him to stand up and face the wall for a few minutes but after doing that and hearing he was sorry I really felt guilty. I know I have been so strict these past few weeks, but I just want him to know what's right and wrong. I know he is just a kid but I want him to grow with the right attitude and all that stuff. Being a parent is not really easy.

I Pray everyday to God to guide my son and bring him to the right path. My son is a really sweet boy but sometimes he just want to do stuff on his own and I guess that's just normal, right? I love my son to death and I am hoping that he would grow up to the person I am Praying that he would be.
