The Story of Me Becoming a Grandparent While Still Single

My family is a bit unusual. My father is the youngest in his generation, so the age difference between him and his eldest nephew (my cousin) is not significant. Since my father and his eldest nephew had children around the same time, my age and my cousin's son's age are similar. To be precise, I was born first, and my cousin's son was born a bit later. Then yesterday, my mom said, "My cousin's son had a daughter." He had a baby girl. So, even though I'm single, I've become a grandparent through my cousin's son having a child. They call this a great-grandparent. Ah....😮
