Somehow we managed to keep a big secret from the little people. We drove to Paddington and the toddler and I went off to look at the big trains. We saw inside the cab of a huge train, went up and down escalators, and ran after pigeons – him, not me.
Then a train came in and we watched the people walking along the platform until we recognised a very special person – Grandad! We got back in the car and surprised Little Sis and went for lunch before a spot of house hunting.
