I found myself impersonating a youth the other night.

As I queued up to buy a ticket for an RSNO concert a chap offered to sell me one that was spare because his chum was not going to be able to make it. I assumed that he was selling it at half price in an attempt to minimize his losses. Later I discovered that I had in fact purchased at full price an "under 26" concession ticket.

The fact that I passed the ushers' scrutiny I find most encouraging.
