What is a specific moment/event that made you realize you were truly "a grown-up"?
I have a couple.
1) Shortly after our first wedding shower, I started packing up all of my college dishes to give away to a college student. I realized that I was putting 'grown up' items away. Years from that day I would tell the story of who gave us what items for our wedding years ago. I would look back fondly of that time and be able to tell my children the same stories my Mom told me.
2) We hired a high school student to do some filing at my work. It didn't take long for me to realize I related more to her Mom than to her :-/
3) When becoming a Mom. With a daily routine for cleaning, work and home.
