A wondering

So, last night Dwayne had a serious thought that made me giggle when I heard it.  He asked out loud if the usually well behaved kids come home with rotten behaviour, do the kids who usually exhibit rotten behaviour come home and act more well behaved and use better manners?  Haha!  I had this mental image of reformed bullies and brats coming home to astonished parents.  Does anyone know?  Perhaps behaviour swapping occurs like lunch bag swapping... ;)
