Sorry to hear that your sister has died. She saw out Christmas, she saw in a new decade, she saw snow and for the short periods of time she was awake, at the end, I'm sure she saw love.
RIP Gloria.
RIP Nan.
RIP Stephen (died at 33 - no age at all)
RIP Mike, Chris' dad (42, I think - again, no age at all)
RIP Lily
To name but a few...
Cancer does mess up so many families, doesn't it?
