Our house was too big anyway

P.S. I think I have mentioned that we are using our super enormous house as a 2 bedroom, 2 playroom, 1 living room, eat-in kitchen lay-out. Well, for the past 2 days we have only 1 playroom, as Seb managed to lock the door to the downstairs playroom... None of our tools will jimmy it open, so we are hoping that Matt our friendly contractor (with a 5 year old himself) will have a solution. We can look in and admire the toys through the French doors but no playing happens. In fact, every door in the house has a lock on it; obviously the renovator wasn't thinking of a family with kids.
