What did we miss?

Everytime I look at his picture, I can't help but look into his eyes and ask him "What did we miss? What didn't we see?"

The "What ifs...." and "If only's..." have started. But the "What did we miss?" haunts me the most. What didn't we realize? The useless gift of hindsight gives me more questions, and fewer answers. I wonder if he had bi-polar disorder and we just missed it. Was he depressed and hide it well? Was it just one more party, and this one went terribly wrong?

Why?
Why?
Why...

If only...

If only we could go back...
If we only had one more day...
If we had said less...
If we had said more...
If we did this and didn't do that....

What could have made a difference? Could we have made a difference? What magic words would have given him less confidence in being invincable, and more belief in possibly tragedy?

Why can't we turn back time?
Why don't humans have reset buttons?
Why wasn't our love enough to bring him back, to save him?
