I'm the dad of YOURNAME, and my child is in class X at your school. I'm writing to tell you that I've decided to send my child to school, even though there's a pandemic going on. I want you to know that I'm fine with this decision and I give my permission for it.
I believe that my child will do everything the school asks to stay safe from the virus. I promise that I'll make sure my child follows all the rules and stays careful.
Thank you for understanding.
