Where did you stay so long? Saw something useful?

That's how long. - I saw that.

- What took you so long? - I saw her again.

It is long since you saw daylight.

It has been so long since I saw you.

Actually not long ago, I saw something I shouldn't have.

It has been so long since I saw you...

It's been so long since I saw it.

It's been so long since we saw you.

I had a dream not long after I saw this.
