What You Don't Know Won't Hurt You.

Here's what I think. If there's something you think you shouldn't tell someone, then don't tell them.

This can be difficult. Kids in general, for example, have a really hard time keeping secrets. As soon as they know that something is a secret, they'll be bursting to tell someone.

Not just kids, of course. I'm sure we've all told someone something we regret.

Talking too much can be detrimental. Promises get broken. People get hurt. You end up trusting the wrong people.

Nothing good comes out of telling someone something that:
(a) They shouldn't know, or,
(b) That if they know, no one will benefit, or,
(c) That if they know, it will hurt/worry/negatively impact them.

Of course, this is all within reason. I'm sure you can think of a million examples in which this does not apply. Especially for (c). Because sometimes people just have to be hurt.

But as the saying goes, in general, what you don't know won't hurt you.

Better to keep things inside.

Seriously.
