Sammi continues reminiscing, “I remember fun times with them and all the laughs we had, and it was a time in my life that I really loved. I enjoyed being there at the end of the day even though I was going through a little bit of something. There were positive times and fun times.”

“We were all brothers and sisters, and I miss it,” she acknowledges. “I miss being a part of that.”
