Here is my mom’s comment when she read my post (It’s a little intimidating to have your wise mom reading what you write, but I’m glad she does.)
I suspect you may have made a simple problem more complex than child could emotionally handle. She lied, she needed a spanking, she needed to be reminded that good intentions arent the same as right actions. Hug kiss problem over. Howevr, said child needs to have room checked more often by mom.
