Nina was such a nice lady but tough as nails. She and I would talk recipes for hours. Italian food of course. She brought me homemade cookies, eggs from her chickens and a bottle of wine. I will never forget her kindness and generosity. She loved my dog Lily and I would bring her over to visit. The pup would jump on her and give kisses. Nina used to laugh hysterically. She was a neighbor and a friend. I will miss her. My sincere condolences to her family, especially Frank and Anthony.❤️✝️ Love, Joe Alba
We will be praying for you and your family. Love Lynn & Joe
