Sorry Bob.

I have to lay some guilt off my chest.  Back in 2006 in the quarter I was about to graduate from University, I had made an unfulfilled promise.  I was working as a student assistant at the Center for International Education Department on campus.  I had made acquaintances with Bob, one the University Courier Personnel.  Bob was a white dude in his late 40's wore sunglasses all the time, had a small frame with a mid-aged belly, wore a silver wiry ponytail consistently in his every day repertoire.  He was generally a very open person willing to chatting to any and everyone.  In our numerous sessions of small talk - Bob came to know of my post - graduating plans of taking a 2.5 month backpack trip.  One day, he handed me a $10 (or $20) and told me that I needed to promise that I would send him a postcard from every country visited.  Guess what? I promised, said goodbye - and I never once sent one postcard.  To Bob: "Sorry, Bob - I never fulfilled my end of the bargain.  The guilt will haunt me forever"
