I say to people who care for people who are dying if you really love that person and want to help them be with them when their end comes close. Sit with them - you don't even have to talk. You don't have to do anything but really be there with them.
I'm sure most of us remember being a kid and you have all of this endless time where two weeks before Christmas feels like ten years. I used to go to bed to try and go to sleep to try and make it go faster.
