loss.

Yesterday my youngest brother lost one of his best friends in a terrible motorcycle accident.  This boy was his travel companion while he was in New Zealand, and his current roommate.  On the same day my brother also found out that he got an awesome job that is perfect for his recently accrued major.  As he packs up his friend's belongings to send back to his parents in Iowa I can't help but feel incredibly sad for him.  I know that I have no right to cry for someone I never knew, but is it okay to cry for my baby brother - who is still alive, healthy, and having to go through such loss in an intense and stressful time of his life?  Is it selfish of me to feel sadness for him, when I still have him alive and well?  I can't decide.  Until someone tells me otherwise I will sit here and shed tears for the brother I love and the friend he will miss.
