What is the threshold?

I finally cracked last night. I was overwhelmed by grief.

It took me almost 12 days to finally realise that I have loss someone who has been an important feature of my life.

I cracked and realised that my threshold has been expanded to quite an extent.

I find it interesting to experience a re-learning of my experiences and having a deeper understanding of myself, especially in unravelling "Who am I?"

"What makes a man?" and "Who am I?" seem to be my pre-occupation these days. And I wonder "Why?"
