As hard as this is, I know you are at peace now Colleen, and with Wade.
You’ve wanted this for a long time, and though I am sad you are gone, and will Miss you, I’m glad you are no longer suffering .
Love you sister 💔. RIP
So very sorry for your loss of Colleen. May she rest in peace 🙏
I knew Colleen her entire life. When I moved away she would write, call & visit. We shared a lot & I do have many, good memories. We did seem to have a lot in common- each being mischievous. Hopefully she is no longer in the pain she has felt for so many years.
Colleen was always so good to us kids! I loved to see the smile on her face everytime we brought her grandbaby around. Be at peace and let the boys know we all miss and love them very much.
Love You Coco!
