It's official, I am an idiot

I can't believe it.

Three months ago I was invited to attend a private reception followed by a concert and supper at the Royal Festival Hall.

We were promised a "fabulous evening of Hollywood Soundscapes" and "entertainment inspired by the glamour of Hollywood".

Better still, "Our post-concert supper promises to entertain and enlighten with our guest speaker Joanna Lumley providing a fascinating insight into working in show business and alongside many Hollywood greats".

I was really looking forward to it.

But last night, as the London Philharmonic Orchestra played their Hollywood Soundscapes and Joanna Lumley stood up to entertain and enlighten, I wasn't there.

I got the date wrong. I thought the event was on Friday 21st October.

How could I have been so stupid? I really am a complete idiot.
