Who is PAN to me

He is my only best-friend. 

The only person I could really be myself with. 
There was no limit to the knowledge we shared, every single day, by email, call, face-to-face, while swimming, while eating, while walking. 

We never had a quiet dinner. 
It had come to the point that if I was to express a business idea with a detailed plan, he would challenge me so hard, corner me and... start smiling. 

Go on, ask the few dudes-from-hautes-etudes, he took on for a training. 
Some gave him the nickname of Tempest. 
Not every one had the privilege to do a one-year training, for free with housing and F&B. 

Some quit after the 3rd day. 
Some didn't even make it to the 1st day. 
I can't remember if and when and how he told me he was proud of me. 

 How he often hold my hand, is how I felt he was proud of me.
