As fate would have it,

 

I bumped into O this morning on my way to work. I live behind the train station and our school is across the street from it, so I walk in the back and out the front of the track area everyday on my way to work. When I was half way through it today, I saw O entering it with his duffle bag and daypack on his way to the track his train was leaving from. We both only had time for a very brief exchange of cordialities and a handshake, then we went out separate ways.
