I don't know Rob. I've had several friends/acquaintances depart over the last couple of years.
I think it's something we never think about happening when we are younger, but as we get a little longer in the tooth, well, it starts to happen, we notice and it hits us harder.
I try to make sure I think about them every now and then and let them know that they may be gone, but not forgotten, and that they left a mark on this world.
That's all I've got. So sorry about your loss...
