So I put this to my twin sons who were seven years old at the time - the offer was a weekend away for each of them on their own with me, anywhere, doing anything. They would be in charge. Where would they want to go? What would they want to do? I expected to have to moderate their choices - no, sadly this time we can't go to the moon for the weekend in a rocket, or to Disneyland Florida, or to see the pyramids in Egypt or in a hot air balloon over the jungle.
