We've gotten ALOT of comments DS lately because DS7 has taken to carrying around thick chapter books with him where ever he goes. And we have the opposite situation. DS is in first grade, but could easily pass for a kindergartener. He literally read an hour the other night in a crowded room of people and a bunch of people came up and commented. People would ask him what he was reading and then he'd give them the look that said - don't bug me, I'm reading a good book and just flash them the cover. Guess we need to work on manners! We've also gotten a couple of comments this week on vocab. But generally, DS tries to mask vocab and ability when playing with other kids. Only if an adult goes out their way to engage him in more adult discussion does he "come out".
The saccharine voice thing drives me nuts too! It sets both my kids off. They become immediately belligerant if they get that tone.
