I remember how strong you were, and although you were two years younger than K you were quite an even match with her physically from quite young.  The two of you mainly got on well together but you did sometimes fight.  You were both pretty determined, and teeth and nails would come out on occasions to supplement the wrestling.  But neither of you were tell-tales and you rarely resorted to using parents as referees.  I believe you seldom fell out for long though, and by bedtime you had invariably made your peace and were back to being friends
