We had a picnic on the lawn outside once the confines of walls became too much for Henry.
And then we went to a mall to buy a toaster. The funny thing is that in retelling my day to Greg I described the mall moments as being fairly incident free. And it was, except of course, Milly and Henry tore around under all the clothes racks, Milly discovered she could pull clothes off hangers with a big jerk and they would make this really funny thwop, twang sound as the hanger springs out from the shoulders, flies up and the clothes heap up on the floor, they hid under a display and knocked over all the shoes stored underneath (at least they are playing together nicely), Henry smashed a bottle of nail polish on the floor and when Milly refused to go any further because she wanted to go up an escalator and flopped and flipped and yelled on the floor in the middle of an open area, Henry and I joined her in a big pile together and it was really funny.
As far as my kids go, that WAS incident free.
And we even managed to buy that toaster.
