Half Full or Half Empty?

Starting to quite like the journey I've been taking because of the strikes. Rather than changing at London Bridge, I've been getting a different line direct to St Pancras. Longer journey but nice to simply chill for 50 mins on the train and read. While waiting for the bus outside the station, I watched a man dig a tissue out of a bin and proceed to blow his nose with it. He didn't look homeless, wearing nice brogues, but looked a little lost and sad. I almost wish I had asked him if he was okay!
