Moo: What are you doing?
Me: I'm making your pajamas, out of elephant fabric.
Moo: Oh! elephant pajamas! I will be delighted! I will be delighted and so surprised!
Delighted means happy. I will be so happy with my pajamas.
(Pause)
Moo: How about an elephant nighttime cap? I would be surprised and delighted with an elephant nighttime cap too.
