I visited my parents today, a bittersweet experience and one that I'm almost glad not to repeat. My father hasn't got long left on this world and my mother - I think her heart will break long before her spirit. She asked me not to visit them again, she doesn't want my memories of them to be blighted by seeing them sick. When she gave me a precious, hand-knitted blanket to take with me as something to remember them by, I had to choke back my tears. My parents are everything to me, but I know that by staying on Earth I might well be signing my death warrant right along with theirs.
