Is Ignorance Bliss

I think that in some cases ignorance is bliss. There are some things some people should not know about and then there are some things you should tell people it all depends on the situation. Say for instance you seen one of the guy’s girl up on another dude not in no friendly type way, you should let him know about it cause keeping it from might cause problems between the two of y’all. Now in the case were there are things that people shouldn’t know like say you  been telling your friend that the person they talking to is not who they think they is and they just don’t want to listen, well this is where ignorance is bliss and you are able to just keep your mouth close without no consequences.
