Usually I'm all for waving the flag about having boys instead of girls. The general rule is that girls are easier all but a few years, but those few are so thoroughly miserable as to make boys worth it overall. I briefly had foster daughters for a few months each - one eight, one seventeen - but I can't say I really know what I'm talking about with that group. My forays into coaching or directing girls' or co-ed groups were of, uh, mixed success.
Boys I understand better. The flip side of that is that they understand me better, which does not always work to my advantage. Dave Barry has written persuasively that males have a joke-storage part of their brain which seldom exists in women. In the event of any tragedy or national emergency, men spring to the fore to tell jokes about it. Even "better," they immediately network with other men to share these jokes from the Redwood Forest to the Gulf Stream Waters and all that. They tell jokes and they remember them. It is painful to watch most women trying to tell a joke, forgetting important parts of the set up or doubling back to correct themselves.
For a father with sons, this becomes a burden. I have dozens of reusable lines that are clever when first heard, but are admittedly tiresome or even grating when you've heard them, oh, several dozen times. In the wide world, most people get to hear the line but once, and if twice, then long separated. My sons get to hear them many times. One son in particular, who is either blessed with a more prodigious memory or thinks he is, or both, is no longer amused. A particular favorite of mine when a small child is out of sight of his parent and moving quickly is "Somebody's going over the wall, warden." I love that line. Yeah, I wish I'd had it when the children were small.
The Son With Exacting Memory points out "You say that every time you see a child running." Well, that must be a bit irritating, eh? eh? I said 'That must be a bit irritating, eh?'
If daughters are like wives, then I might get to hear something much more encouraging, like "What's that thing you say when you see a child escaping again? Something about around the wall?"
