Not so certain about the wonderful

It was a complete surprise for her. Without going into great detail, we have a weekend house and a weekday house. She got the Birthday presents that I could smuggle into the car on the morning of her birthday, which she was not expecting, and when we got back to the City house, I told her there was another present where I had put it. She went and had a look and was quite elated. "What I always wanted" sort of noises.

The problem now emerges that I have to think of something for the next few decades of birthdays and Christmases......
