Hahaha... That sound sounds exactly like my wife and I!
And I thought that might be the problem here for Calvin too... It's a psychological/mental thing. If he could run around, the hyperactivity could kick in (FUN!!)... But for heaven's sake...sitting in this boring classroom, listening to that previous (never-ending) chapter...and now he even has to move...to the next boring chapter!!? Will this ever come to an end😅??
