The girl is using some "Free Time" on the piano today.
(The kids get 10 minutes of free time for every song passed. This means they get a one day reprieve from practicing a new assigned song. In theory, it motivates them to pass a song and not mess around.)
So my girl leafed through the piano books and found some Christmas carols. She opened up The First Noel and starting plunking out notes.
Me: What's your time signature?
She: Um... 3/4.
Me: So you need to count, "3 and 1 and 2 and 3 and 1 and 2 and..."
She, with a look of amazement on her face: How did you know that it started on 3???
Me (obviously joking): Because I'm amazing.
May they continue to be amazed at my "vast knowledge" for at least another couple months before they find out I'm a fraud, totally faking this appearance of knowing anything.
