There was a PTA-sponsored Kindergarten welcome event at the school this afternoon (and since I know you're wondering the answer is yes, I did organize it). Child 2 made friends with every other child there, one in particular. The other kid's mom took a picture of the two of them and I said that was awesome because in 10 years when they're sneaking out of the house to go get drunk we can show them a picture of the day they first met. He met his teacher, hung out in the room and then he didn't want to leave. All in all I'd say these are all very good signs of things to come.
In other words: urge to kill fading... fading.... fading....gone.
