To Joan and Mary’s brothers,
I’m so sad to read of Mary’s death last summer. Life wasn’t always easy, but Mary was a survivor. Resilient, and strong. She frequently put others before herself, I wish she’d been selfish and met her own needs. Learning to embrace life One Day at a Time. Unfortunately, we lost touch in 2012, she wasn’t accepting of help I tried to get her. I’ve never forgotten her. I still remember her phone number, 335-4582. I’m so grateful Mary’s funeral was on You Tube, I sit here blubbering. Mary and I had much in common, both nurses, loved our dogs. We met through a gastric bypass support group. We used to walk my Cairn terrier, Harley and Mary’s much loved “1 eyed Pekinese,” Nikko in Hingham, I believe it was at a park called Land’s End. Once we got off trail and little Harley ran up a hill and looked all directions. He ran down the hill and proceeded to lead us back to my car. Mary called him Scout from that day forward. She laughed that it was a good thing we had Harley as we truly would have been led by the blind if it was left to Nikko. We twice walked the NKF walk in October. Mary was working in Dialysis and my husband was waiting for kidney transplant which he received in 2012. Both our dogs wore t-shirts,
“I Walk All Over Kidney Disease”
“Paw’s for a Cause”
Mary loved her home at 45 Norma and loved her neighbors, some she’d known since childhood. We frequently shopped at South Shore Plaza, at Talbots and Thursday nights at a shoe store in Quincy Center Maria’s. She loved shoes! I was her project at times, she enjoyed picking shoes for me. Sometimes she sent me to Lord and Taylor and I bought shoes from Joan. We planted flowers, hung out by her pool. Mary loved Christmas and decorated like crazy. Joe thought Mary and I were crazy, and indulged our antics. We had back to back appointments at NEMC for years, then went to Castle Island to walk and talk.
Rest in Perfect Peace Mary with Joe.
Love you.
