Hints:

Just a second ago. You couldn′t miss her.
You sure you didn′t see her? I didn′t.
I didn′t.
What mermaid. Watch, just watch.
You′ll see.
Well, she′s there, I know it.
Where?
She′s shy.Shy?
She′s afraid.
Of what? Of us.
She is afraid to come out with all of us here.
Let′s all go to sleep.
But how would we see her if we all go to sleep?
We just pretend to be asleep.
