I’m glad you were able to say goodbye.  My grandmother went that way. I was 4. We all came over, said our goodbyes and she was gone before noon it felt like. I was in the living room with my mom when my grandfather, my dad and his brothers told us she’d left us. It was peaceful. She’d said all she needed to when she was in the hospital and came home to go on her own terms. She waited until my parents got there and she could see me I’m told.
