25 years ago my Mom married Harold. At the time we were happy for them but we had no idea how much we had to celebrate. So when the chance to celebrate their silver anniversary came around- we threw a big western themed party!
One of the hidden benefits of having Harold join the family, was the fringe benefit grandparents. Grandma Vernie immediately accepted that she had two new granddaughters. She bought us Christmas presents that year- pajamas and a jewelery box that I still have. Then she kept my college mail box full with letters from Iowa. Today she's happily Grandma Vernie to an entire generation of little people. And there is nothing "step" about it.
