Last year my child purchased

Last year my child purchased a big diamond paperweight that said “Mom”. He bought it for my step-mom who has never birthed a child. My stepmother is known for being vocal about not liking gifts. I told Kyle that it didn’t say “wow” but “mom”. He replied, “She’s someone’s Mom!” My stepmom looked at the gift oddly and teared up when I told her the thought behind the gift. She proudly displays it on her entryway table which is not something she would normally do.
