Well, I'm always hearing about this "no child left behind" stuff and pushing kids through school when they are not prepared. He was in my son's 1st grade class and we just happen to find out that he failed because we stopped by the classroom while we were at the school meeting my son's 2nd grade teacher. He loved his 1st grade teacher and wanted to say hi. He also plays soccer in the same league as my son so we bump into him at soccer games.
Just from observing him, he seems to act younger than his age. Not that 7 and 8 yr olds are all that sophisticated, but he acts more like my 5 yr old than my 8 yr old.
