I DON'T KNOW!!!!!!!
I guess I will go back and look at this some day.
I am self medicating today.
I hurt too much and there is nothing else I can think of that will turn off the pain, if only for a tonight. I tried playing loud music, that didn't work, even Pink Floyd didn't turn off the hurt noise!
Tomorrow I will have a headache and I will be tired, but even that is better than the pain I feel for the loss of my friend and his family.
