1. At the moment the singing man's lyrics are: 'Sorry to bother you, to bother you, to bother you, so-o-o-ry to bo-ther you.' He sings 'Sorry to bother you' to everyone he passes and opens shop doors to sing it people inside. Sometimes he pauses on the pavement, one hand in the air to give a little recital. It's funny to watch different people's reactions as he parades down the street - a youth in the shop opposite got the giggles; some people reply 'That's quite all right'. Other people jump - it's a bit ironic that they have been bothered by him apologising for bothering them.
2. When people understand how important it is for a girl to be allowed to share their pudding even though she didn't order any for herself.
3. Walking in the dark because your feet know where to go.
