For people you believe you’re trying to protect yourself from
I don’t think telling them anything in the first place is required

But if one is to open up to someone
I believe they should do that
But there are people you don’t trust
And I think nothing telling them things is better inside of half truth they they can use against you in the future
But when it comes to relationship
I believe full truth is better because when half truth starts and the trust is lost, it’s very hard to get back on track
