My husband and I were sitting at the table finishing up our lunch while the boys were playing in the living room (not unusual at our house).
I heard grunts and cries from behind me of someone "not getting their way", so I turned and looked.
Me: (with tiredness) "They're fighting over something.....
 (with awe) "Look!  They're wrestling!!"
Husband:  "Wow! That's really interactive!"
