My aunt used to say that my step dad will be happy as long as I got him a card with a nice verse inside and it saying happy birthday dad. Not just happy birthday.
I will take back what I said about saying step dad was flawed. We are all human.
Compared to my biological father, my step dad was a saint. He was a good dad without being compared to my blood father.
My step dad taught me how to ride a bike. He is funny. He would explain why he got too emotional or not emotional.
My step dad treated me and my brother the same. I would never call my brother my half brother and he says I'm his sister.
