All of you are very kind. Thanks to all who have wrote here. I am a little emotional right now. When you go through something like this you do a lot of reflecting. You begin to think of how trivial some things are and the importance of others.
For many life means little. People are killed over a few dollars. I recently seen a wallpaper on flickr of a man shooting a person at the edge of a cliff and how others commented on how cool the wallpaper was. It was a vector wallpaper and many would shrug it off as art but not me. It depicts something real and the reality it depicts is hate and that life can be disposed of like a piece of trash.
You may ask what this has to do with my sister dying of cancer. I guess directly it has nothing do do with it. Cumulatively it has caused me to reflect about how fragile life is. There are no guarantees about how long we have on this Earth. That is why it is important to live life in such a way so there will be no regrets or at least as little as possible. When you have made as many mistakes as I have it is hard to not have some regrets. The past is the past though and today is a new day God has given us.
Sorry for my rambling, like I said I am a little emotional right now.
