Hi VPM, my two boys also squabbled as kids, one was a little demolition expert the other a mini construction engineer -

As adults they are both best of mates and both very capable, good parents, practical and intelligent one has a good job and travels a lot, the other is self employed and sorts business IT problems. As I am peace loving it drove me nuts too, but now very proud of them both, so take heart they will hopefully grow out of it.

Sit down before a fact as a little child, be prepared to give up every preconcieved notion, follow humbly wherever and to whatever abyss nature leads, or you shall learn nothing.
