Who are you to say that?

I promise no to tell anyone.

That's what I'm saying.

What have I told you?

Some things are better left unsaid.

Don't tell anyone where you're going.

It's easy for you to say.

simply put

- I can't understand why she never calls me. / Не могу понять почему она мне не звонит.

- Simply put, she's not into you. / Проще говоря, ты ей не очень нравишься.

What makes you say that?

That's what I'm talking about.
