Meh. I think this whole discussion is pointless...
Hehe, I do too. But I'm enjoying it, so please don't take my continued wall-of-text as anything hostile, just a further narrowing down; which is fun for me (though it annoys the hell out of my wife, hehe).
Judge Intentions. Okay, the Santa Claus verse Intuition was wrong. Should have been Santa vs. Logic (what do I know vs. what I'm being told) and we're all agreeing (I think) that Logic goes 1,2,3 for the young age categories.
In reading up on Intuition (SR4A, pg 67), "A character with little Intuition may be unobservant, may rarely think things fully through, or could simply be 'slow.'" Other than the unobservant, that sounds like the average kid....especially the rarely think things through and less so on the unobservant. So I'm still liking the
average youngin' Intuition to progress at 1,2,3.
Yeah, I'm assuming I'm average for sneakiness (though I like to think I'm the shadow of your nightmare's shadow! hehe), but Perception's liked attribute is still Intuition and I tend to sneak on kids better than adults.
What's funny is I was assuming that the "no, no, no" attitude of little kids would speak to a higher Charisma, but SR4A, pg 67. "A whiny demeanor, a me-first attitude...are just a few traits that can give a character a low Charisma." Hehe, everyone hates the kid the store yelling, "BUT I WANT IT!!!"
What's nice about the 1,2,3 approach is that by bumping one or two mental attributes to +1 of the average that really speaks to their personality.
Now giving kids Con skill with Lying Specialization...perfect.

Especially for the middle kids, they have to learn to manipulate the adults to get attention because the youngest are the newest and the oldest have the established order.
