Yes pr... and Maharaj give wonderful shastric references :)
The people we live with know our heart. If we are really sincere they know it. And if we are struggling and have no taste in Bhakti, that also they know it.
Maharaj also said in the lecture that specially children, they can understand everything very well. The reason is, grown ups already know all the things, so they dont take anything seriously, but children have empty mind, and they are learning everything from beginning, whatever they see and observe is the only thing they know. So if they see parents fighting or are envious towards anyone, it has very negative effect on them.
Children do not know whats going on in the outside world. Their parents are their world.
Your servant
