I second the congratulations. For me, becoming a grandfather was a significant milestone in my life, and I pictured myself differently than I did before. After all, I was now “Grandpa,” and everything that entailed.
Congratulations! Now where are the pics? It’s a rule you know.
I’ll never be a grandma, as I had no children. But I was there when my dad and I heard a little baby crying through the door where my sister had been in labor. He turned to me, with his eyes shining like 200 watt bulbs and said “did you hear that? DID YOU HEAR THAT???”
