In our house Mom and Dad were equal: neither of them received a card for Mother's day or Father's day. Mom, a JW, thought it good, Dad had to put up with it. Being a child in a "divided household" was hard, at times unbearable.
My Dad never understood and it is just today that I'm coming to understand myself. Today, I understand that it was just a day for Dads and nothing more. It was not wrong. But it's too late to tell my Dad this. Sorry Dad, I did not mean to hurt you though I know I did.
Your son, Frank.
