MM is out running errands while the boys enjoy a “do nothing” day.  The boys are playing nicely together (a big change from yesterday), and I asked TD2 to put one of his toys in his room because TD3 already broke the same toy and we replaced it.  TD2, in an abundance of caution, decided he really didn’t want TD3 getting into their room (TD1 and TD2 share a room).  So he locked it.  From the inside.  We have the developer’s “key” to get into the doors, but I’ve never been able to use them… they take wiggling and jiggling to get the lock to unlock.  So, TD1 and TD2 are locked out of their room until MM gets home.  I guess that’s what TD2 gets for being “clever.”
