We took care of my Mom at home when she became terminal. My stepfather, my two younger sisters and my younger brother were caring for her at the end and my sisters woke me from a nap in the chair to tell me Mom had passed. As you can imagine my sisters and stepfather were a mess. I went over to close Mom’s eyes and whispered I love you. Much to our surprise, since she had not been able to speak for a while, she said “I love to you too son” and then she was gone. Miss her still all these years later and have no idea how she managed to say that.
Sorry for your loss.
