My father’s friend complained to him that his OTD son has a bad influence on the other kids. My dad told him he should tell his son that he loves him and he’ll treat him like the rest of the kids. ON ONE CONDITION: He shouldn’t involve his siblings with his actions. He should advise them to stay away from the path he chose. (Not exactly sure if that’ll work)And he shouldn’t persuade them to come with him to do “stuff” etc..
Hatzlacha in whatever you do, and may you have lots of nachas from all of your kids!
