Seen: Kilburn tube station, at the weekend.

One man dressed in a natty pin stripe suit and bowler hat, swinging his umbrella as he walked. He stood in our carriage for two stops, before turning to look at everyone, smiling and wishing us all a good day and 'cheerio'!

It turns out he is a school teacher on holiday who is trying to help people feel more comfortable travelling on tubes since the bombings, and by dressing up people respond to him and interact with each other after he has gone. Fabulous!
