I'm sorry man. I lost my mom a few months back and it was terrible. Spend as much time with her as you can. Talk as much as possible. Reminisce about life. You won't get another chance.
Most importantly, help her get her affairs in order. The bloodsuckers come out when a person dies, will or no will. Get everything hammered out with her input so that her mind is at rest in the coming weeks. Do as much as you can money wise right now. If you wait you could be subject to (((taxes))).
We went over documents some time ago, everything is in as good of order as I can make it without taking it over. My father will be a problem, however - he has no idea what goes on with the finances.
