I'm very sorry to hear about the loss of your friend.
As mentioned above, we often don't know what someone else is going through.
I offer my condolences and I pray for you and for the gentleman's family and loved ones.
OMG, Evan. I am so sorry. It never makes any sense .... not to those of us left behind. This situation has touched my family personally. If you want to talk, or want someone to listen, shoot me a PM. In the meantime, I'll be praying for you, him, his family, and all of those who this personally touched. May the peace of God be with you. Prayers on the way.
