Here is a scripture that I find comforting in times like these.
57 The righteous perishes,
And no man takes it to heart;
Merciful men are taken away,
While no one considers
That the righteous is taken away from evil.
2 He shall enter into peace;
They shall rest in their beds,
Each one walking in his uprightness.
(Isaiah 57:1-2)
The RAM stick thing is pretty cool. There's nothing wrong with having a sense of humor about death. Do you think he would want you to be sad for long? Of course not. So don't feel bad about continuing to live your life, because that's exactly what your friend would want for you. Remember him, and honor his memory by learning whatever you can from his early passing.
You will see your friend again. When he wakes up, it will be in a world filled with justice, mercy, light, and love. Sometimes God takes people early so they will not have to live in a world full of evil and suffering...maybe that's what happened to your friend. May God bless and comfort you and your friend's family.
