and your child says he hasn't?
DS1 borrowed a game from a friend his. According to the friend and his mother the box had 2 games in it - the one DS1 thought he was borrowing, plus another. According to Ds1 though, there was only 1 game in the box.
WE - DH, the DSes and I tidied their room last night and there is definately no sign of the game. The boy came round last night while I was out and DH told him that we didn't have it. SO then his mother turned up and said that the game had been in the box, and we had lost it so could buy him a new one!.
DS1 is really upset, and is thinking that we don't believe him
