reassurance

Well, Reuel's cousin Nancy just informed me at lunch that her younger son used to crawl around with his mouth open...in preparation for trying to bite his 2-year-older brother.  And the older one would shove the younger one out into the street while they were walking to the bus.  The younger one would be upset because his older brother was trying to kill him.  She said this kind of thing continued until they were about 9 and 11.  Sigh!

I feel reassured that Owen isn't abnormal.  But it's still disgusting, this whole human nature thing.  This sounds like a distinct disadvantage of having boys.
