Why "he/his"? Just curious.

More generally why would you discriminate, the whole point if there is any point at all to this anal tradition is that at least the folk in the neighbourhood interact a little and why would you want that interaction to be anything less that warm, nice, welcoming and nice-to-meet you ... which is all a bit of dress up and theatre is intended ultimately to promote.

I'm with you, though. I have 10-year-old embarrassed to dress up and have fun with his 6 year old sibling. He's afraid of appearing childish methinks. And yet there are adults here wandering around with troops of kids dressed up too. It doesn't rest well with me, this odd shame the 10 year old has picked up, presumably from peer groups.
