She is delighted!

So am I!

Because she is delighted,

I am delighted!

Why would/should I be delighted

because she is delighted?

If you are delighted because

the other person is delighted,

there has to be only one reason

and that one reason, you know and I know,

the whole world knows.

YES, the same!  Your guess is right.

Instead of guessing, let me tell you.

I SONDER YOU! .
