AITA for telling a woman her baby is not a miracle?

15F here.

My baby half brother was born a few months ago, my step mother has baby fever right now and is arranging mommy and baby events at the house when she keeps inviting other moms and babies around. I don’t care, they can do it as long as they don’t bother me. She usually wants me to help with prep and clean up which I don’t like doing as it’s not my problem and they’re not my guests.

Anyway. This last weekend there were this woman and a baby and she was going around showing the baby to everyone and asking them “is she not a miracle?” And honestly it was obnoxious. But I wasn’t rude and didn’t say anything until I was getting out to see my friends and she stopped me and asked “is she not a miracle” and offered me the chance to hold the baby. I asked “you want an honest answer that?” And she said yes. So I said “no. Tens of thousands of them are made every day, it’s the furthest thing from a miracle.”

She was annoyed and said I was short sighted and rude. I didn’t say anything and left.

Later that night my step mother and dad told me I was rude to their guest and I should have reassured her that her child is special because she is special to her. I honestly don’t care. But they wand me to call her to apologize and I don’t see why I should. She was the one who stopped me and asked me a question, and I offered to bow out but she wanted an honest answer so I gave it.

AITA?
