shrug.
Perhaps you are constraining the "why" too much.
For example,
-Why is he going to see his girl friend?
-Why does he love her?
-Why does she love him?
-Why is the child in the road?
-Why didn't the child's parents care he/she were out?
-Why is "Why" of no relevance?
-Why do you think that belief in God is "shirking"?
You see, I could go on all night
