I'm an idiot

All set for my trip to Brighton, to see Fred's Christmas celebration at kindergarten, and to go on our little planned theatre trip together. I was waved off outside the airport and off I trundled.

Only to find I had forgotten my passport. Duh.

My daughter made a great effort to get it to me in time but without success.
I watched the gates close and the plane went off without me.
I have never been so cross with myself!
